Version v2.0.0-beta.3

• Add "Spectral Angle" to simplify cutoff selection
• The binaries are now compiled with a GitHub workflow. Also, they are compiled with -02 so they should be a bit faster.
• The GUI now shows help text in tooltips.
• Other small GUI improvements
• The log file is now stored in the main data folder (it was in a hard to find location previously)
