Migrate to TypeScript

[nam-hle]

This PR is for migrating the package to TypeScript (#146) with major changes (but should not contain breaking changes 🙏):

• Remove/replace all flow and babel packages/commands
• Remove unnecessary JSdocs
• Expose type declarations. The users would not need to @types/table now.
• Reduce the unpacked size by 24% (112.4 kB now), the number of shipped files by 42% (33 files now)

Additionally, the schema definitions could generate from type definitions with third-party libraries like ts-json-schema-generator. By doing that, we can safely remove most of the checking code lines and maybe primitive type checking package like is-boolean, is-number,... But of course, we should do it later :D
