Maintainance update

Now uses Github's env file GITHUB_OUTPUT instead of the deprecated ::set-output command.

update Readme

The last release had trouble uploading to pypi.org. This should now be solved as there were problems rendering the readme on pypi.org

uploading to pypi

• renamed release.py to rmskin_builder.py
• pip installs an executable CLI entry point for use as rmskin-builder.exe --help
• RMSKIN.ini & RMSKIN.bmp files are no longer overwritten, rather the altered copies get put into a "build" directory
• refactored rmskin_builder.py to pass black's default linting (pylint)

fix bad action.yml

found & fixed a bad indent in action.yml. Also corrected misleading name in last step of release.yml example (it does not output the path -- only the file name)

version arg was hard-coded to "auto"

artifact from developing & debugging caused --version argument that was passed to get ignored, resulting in the wrong version number in release assets

fixed verification of layout file to load on-install

title says it all, nothing else has changed

with input args

Added ability to adapt & include a header image (RMSKIN.bmp; must be 400x60 with RGB color space) that gets displayed in Rainmeter's Skin Installer. Implemented input arguments to alter the behavior of release.py. Although, most inputs can be overridden using your repository's RMSKIN.ini file.

Verified works with github workflow env variables

the only planned input argument is "path" for managing multiple Rainmeter repos (workspaces) in a single github workflow

This is working

1.1

Success; (-) debugging prompts action input args
