Adding New props

[palerdot]

Adding a new prop requires some involved changes and writing tests. I have outlined steps to add a new prop below.

Steps for adding prop

• Add the new prop in DEFAULT_PROPS - around https://github.com/palerdot/react-d3-speedometer/blob/master/src/core/config/index.js#L67
• Make sure new prop is considered when configuring the config - around https://github.com/palerdot/react-d3-speedometer/blob/master/src/core/config/index.js#L140
• Typescript definition should be added for the newly added props (https://github.com/palerdot/react-d3-speedometer/blob/master/src/index.d.ts).

Adding tests:

Please make sure to add a new test to verify the new changes. Example tests can be referred here - https://github.com/palerdot/react-d3-speedometer/blob/master/src/tests/index.js#L88. Also, refer to enzyme documentation.

Important:

• Make sure to add a test case (Please refer above section)
• Make sure existing tests don't break
• Make sure the code is linted properly. Run yarn lintfix locally to lint the code as per this project requirements.

Miscellaneous:

Please allow edits from maintainers option for me to update docs if PR is in an acceptable state. Please refer - https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/working-with-forks/allowing-changes-to-a-pull-request-branch-created-from-a-fork
