(pub): publish v1.0.0-alpha.1

- this release is technically "fully backward compatible" because it
  only adds to the API and doesn't change anything
  - well besides the continually fixed dotSize function (see v0.2.2)
  - every SignaturePad change has been minor so far
    - including v2.0.0 since it only broke distribution, not the API
  - buuuut, throttle and minDistance actually would make for subtle
    behavior changes since they change the internal functionality
  - the way props are updated now may also cause minor timing changes
- this release does change the internal structures of the library, so
  if those were being used, they might no longer work
- this release also marks a significant shift in how the library will
  be maintained moving forward, since it now relies on the upstream
  signature_pad library

- also update keywords
