Release/0.4.0 - Githubissues

🪂 Safety Nets for Reverse Mode 🪂

Features

✋ Overwrite prevention: Detect changed files to prevent accidental overwrites when toggling between forward and reverse mode
- New option --force to force overwrite
🔗 Link correction: Relative links are now modified to point to the correct file after transclusion
🕸️ Rework multiple access prevention:
- Check for multiple writes to the same code file over all files/patterns, not only for each individually
- Multiple writes are allowed when they originate from the same code block (all but the first are skipped), i.e. you can now link and/or transclude the same file multiple times
🛑 Improved error messages:
- Show which file cound not be found/read
- Explain problem when reverse mode is not possible due to missing code folder

📛 Renamed CLI option --output to --code for consistency with the config file
🧹 Removed CLI argument --language, as it is not required with the features for multiple output files
🧹 Removed option default_language from Yarner.toml, as it only added block language if missing

🧹 Clean code labels in output. E.g. the path path/../to/file.md is now simpified to to/file.md

🔀 A lot of internal restructuring, code cleanup and simplifications
🧪 Started to add more unit tests
💬 Everything except errors and warnings is now printed to stdout, not stderr
