Stop Taking a Ton of Time Rendering Crash Logs

[sylv256]

Quilt will sometimes refuse to spit out a crash log because it needs to calculate the hash of every single mod (see: BlanketCon '23 with >400 mods).
This is a profile from unascribed where she made a mixin to disable a lag-inducing feature in Create. However, this caused a crash, but Quilt refuses to produce a crash log. In total, it took ~30 seconds.

Sorry for the late edit. I accidentally hit the enter key. Work in progress!

Okay, so:

1. This should probably re-use the hash value calculated during cache building.
2. This looks like it calculates the hash for the containing file for every included file, which is obviously unnecessary (this won't be a problem if we re-use the transform cache hash though).
