Make readme more concise.

Add logo, and some documentation.

Make error messages more user-friendly. Also remove magic constants
within functions.

Implement setFormValues for easy setting of fields.

Also migrated to pridepack because tsdx is already unmaintained.

Proofread README.

The tests do not depend on separate files for loading templates. This is
for the layouts to be defined alongside the tests for easier updates.

The methods have been refactored and documented for ease of use of the
consumers.

Add checkbox on sample form in README.

This adds the motivation on using the library, with the pitfalls on
using other form libraries.

Handle selects, as well as file uploads.

For republishing.

We have added a more meaningful code sample in the README file.

Also, the publishing will happen on multiple registries, just like
`@theoryofnekomata/react-musical-keyboard`

Note on installation.

Include short details on using the library.

This commit adds Cypress for testing the library against a real DOM.

Add files from TSDX.
