Investigate possibility for EIS Toolkit binaries

[nmaarnio]

If EIS Toolkit was compiled for most common platforms, it could make it much easier for EIS QGIS Plugin users to run the tools. No installation or separate Python would be required.

It should be investigated how big effort this would be and what library would do be the best for this task.

Did some testing and managed to build a binary for Ubuntu using PyInstaller. Next steps are to verify if the binary works perfectly and then setting GitHub actions that build it for various platforms
