feat: add Bitcoin standard memo encoding example for bitSmiley and unit tests

[ws4charlie]

Added the Javascript files that showcase the Bitcoin memo encoding process.

This is a simplified implementation that enables the revertAddress option (bitSmiley needs this option). @fadeev you can refine and formalize the code (my JS skills are limited) to ship the API in whatever style you deem appropriate. Thanks in advance!

• Added memo.js to provide standard memo encoding function EncodeToBytes
• Added memo.test.js to unit test the memo encoding. I used command node memo.test.js to run the tests.

📝 Walkthrough

📝 Walkthrough

## Walkthrough This pull request introduces several changes, including the addition of a new test file (`memo.test.js`) for memo encoding functionality, updates to the `package.json` file to enhance testing capabilities, and the introduction of a GitHub Actions workflow (`test.yaml`) for automated testing. Additionally, a new configuration file for Jest (`jest.config.ts`) is added to support TypeScript testing. The encoding functionality is encapsulated in a new module (`encodeToBytes.ts`), which includes classes and enumerations for encoding operations. Finally, the main index file is updated to export the new encoding functionalities. ## Changes | File | Change Summary | |-----------------------------------------------|-------------------------------------------------------------------------------------------------------------------------| | `memo.test.js` | Introduced a test suite for memo encoding with three test functions validating different encoding formats. | | `package.json` | Added a test script, updated dependencies, and introduced new development dependencies for TypeScript testing. | | `.github/workflows/test.yaml` | Added a new GitHub Actions workflow for automated testing on pull requests. | | `jest.config.ts` | Introduced Jest configuration for TypeScript, specifying the test environment and file matching patterns. | | `packages/client/src/encodeToBytes.ts` | Added functionality for encoding data into byte arrays with classes and enums for operation types and encoding formats. | | `packages/client/src/index.ts` | Updated to export all entities from the `encodeToBytes` module. | | `test/memo.test.ts` | Introduced a new test suite for memo encoding using Jest, validating the encoding logic with expected hexadecimal values. | ## Suggested reviewers - andresaiello - GMaiolo

🪧 Tips

### Chat There are 3 ways to chat with [CodeRabbit](https://coderabbit.ai): - Review comments: Directly reply to a review comment made by CodeRabbit. Example: - `I pushed a fix in commit , please review it.` - `Generate unit testing code for this file.` - `Open a follow-up GitHub issue for this discussion.` - Files and specific lines of code (under the "Files changed" tab): Tag `@coderabbitai` in a new review comment at the desired location with your query. Examples: - `@coderabbitai generate unit testing code for this file.` - `@coderabbitai modularize this function.` - PR comments: Tag `@coderabbitai` in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples: - `@coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.` - `@coderabbitai read src/utils.ts and generate unit testing code.` - `@coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.` - `@coderabbitai help me debug CodeRabbit configuration file.` Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments. ### CodeRabbit Commands (Invoked using PR comments) - `@coderabbitai pause` to pause the reviews on a PR. - `@coderabbitai resume` to resume the paused reviews. - `@coderabbitai review` to trigger an incremental review. This is useful when automatic reviews are disabled for the repository. - `@coderabbitai full review` to do a full review from scratch and review all the files again. - `@coderabbitai summary` to regenerate the summary of the PR. - `@coderabbitai resolve` resolve all the CodeRabbit review comments. - `@coderabbitai configuration` to show the current CodeRabbit configuration for the repository. - `@coderabbitai help` to get help. ### Other keywords and placeholders - Add `@coderabbitai ignore` anywhere in the PR description to prevent this PR from being reviewed. - Add `@coderabbitai summary` to generate the high-level summary at a specific location in the PR description. - Add `@coderabbitai` anywhere in the PR title to generate the title automatically. ### Documentation and Community - Visit our [Documentation](https://docs.coderabbit.ai) for detailed information on how to use CodeRabbit. - Join our [Discord Community](http://discord.gg/coderabbit) to get help, request features, and share feedback. - Follow us on [X/Twitter](https://twitter.com/coderabbitai) for updates and announcements.
