Feature Suggestion: UnityDebug support

[UnityDebug](https://github.com/Sl4vP0weR/UnityDebug) is "UnityDoorstop implementation with Harmony patch that converts pdb to mdb allowing mono to read debug symbols."

This tool eliminates the need to swap out the game's `mono-2.0-bdwgc.dll` with a hard to obtain, [potentially unstable](https://github.com/dnSpyEx/dnSpy-Unity-mono/tree/master/unity-2018.4.2-mbe) DNSpy compatible copy, but is incompatible with ModTek. Attempting to run both at the same time results in ModTek failing to initialize and the game getting stuck in a loop as it tries to load modded saves.

This would also simplify onboarding of new modders and ensure that DNSpy debugging remains available in the future.
