loot-condition-interpreter

A library for parsing and evaluating LOOT's metadata condition strings. This library improves upon LOOT's existing implementation in the following ways:

• Condition expressions are parsed into an intermediate representation instead of being stringly typed, which allows parsing and evaluation to be separated.
• State is uncoupled by necessity, and Rusts's concurrency guarantees mean it can be accessed more efficiently.
• Results are cached with more granularity, per function instead of per expression, improving performance when expressions are not entirely different.
• Result caching is guided by benchmarks, so results aren't cached unnecessarily.
• Reading executable versions doesn't involve calling out to the shell and piping several commands together when on Linux.

The code is also not as much of a mess, it's got benchmarks, and probably better test coverage.

The tests need the testing-plugins and the LOOT API v0.13.8 Windows archives to be extracted and present in the repo root.
