Since upgrade from flutter version 3.19.6 to a higher version I cannot compile flutter_libserialport anymore for Android.

`FAILURE: Build failed with an exception.

• What went wrong:
  Execution failed for task ':flutter_libserialport:verifyReleaseResources'.

Does the package need an update to support the latest gradle version?

Hi @zoenie123, try the branch from the PR #109 Add namespace. Works for me :-)
