extractor: support extracting using a folder path (#3422)

Patching up the extractor while working on the launcher, fixes:
- makes it so you can compile successfully given a folder path
(currently assumes your project path contains `iso_data`)
- ignore `buildinfo.json` from validation code.
- fixes an edge-case that could recursively fill up your entire
hard-drive!
- allows overriding the decompilation configuration via flag
- adds a way to specify where the ISO should be extracted to
