[0.6.2] Majority Language in Header

Add majority language for each year in HTML header in README

[0.6.1] Restore Python 3.8 Compatibility

• Make sure the project actually works with python 3.8 as claimed by the pyproject.toml

[0.6.0] Add total stars header

• Add header for all years with total star count (if 3 or more years solved by default)
• Fix on_leaderboard and either not working with --count-as-solved-when flag (thanks to karl-sparks)

[0.5.6] Fix overwrite-year flag

Fix --overwrite-year flag to now work correctly

[0.5.5] Fix path error in windows

Update readme version

[0.5.4] Fix missing self. for repository variable

Fix basic error

[0.5.3] Fix .aoc_tiles not existing, and git repository not being available

• Fix .aoc_tiles not existing when trying to run the script. Initially running.lock is checked in the .aoc_tiles dir, if it does not exist, then it failed
• Git repository not being available. For projects where git is not available now it simply works as intended without git functionality.

[0.5.1] Git add README when using autoadd to git flag

• Highlight part with yellow if placement is in top 100
• Git add README when using autoadd to git flag

[0.5.0] Fix auto-add-tiles-to-git flag, change script to post-commit hook

Fix auto-add-tiles-to-git flag. Change script to post-commit hook.

[0.4.1] Considerably speed up the script 6s -> 1s

This was achieved by:

• Using ProcessPoolExecutor instead of ThreadPoolExecutor when
  creating each day. The latter was mistakenly used.
• Loading the github_languages.yaml with yaml.CLoader instead
  of yaml.FullLoader (speed-up: 0.5s -> 0.1s)
• Removed checking of each file separately if it is git-ignored.
  Now just iterate over all git-tracked files.
