v2.2

New features

• Improved the console output to better handle many puzzles. It now displays progress dots instead of full puzzle names, but still displays errors for unsuccessful solutions.
• Added a --report option for saving a summary of the generated solutions and their metrics.
• Improved solution verification to also detect overlapping parts.
• Added tests, using puzzles from omsim and the recent 24-hour challenge sample/test puzzles.

Improvements to generated solutions

• Added a new assembler for generating linear products.
• Added a new assembler for generating products which fit within a hexagon of diameter 3.
• Pistons are now automatically replaced with arms where possible.
• Many other small optimizations.

Bug fixes

• Extra copies of repeating molecules were sometimes being generated.
• Repeat instructions were generated at the wrong location when a sequence started with a Wait instruction.
• If a puzzle had multiple identical products, they were sometimes dropped onto the wrong output.
