feat: emit inline frames

[Gankra]

just messing around right now...

TODO:

• human output cleanup
  • fix the : in "Found by"
  • add the source file/line to the end
  • add the module to the start
    • tbh I hate the xul.dll! prefix...
    • [ ] check if mozcrash.py relies on it
• tests
  • add a new input minidump/sym that integration tests can slurp up to test output
• docs
  • update json-schema.md
  • add doc-comments
  • RELEASES.md
• api
  • look over the new APIs
  • look over the new fields
  • decide if we're ok with everyone using this API having to .rev() the inlinees (probably not, but it's not a terrible burden either)
    • I was not, fixed
• [ ] builtin dump_syms support
  • [ ] pass --inlines?
    • configurable by a flag?

lmfao sym files

I guess I could try to trim the file to what's needed but that kinda sounds like a pain

some minor comments, looks awesome otherwise
