feat: fuzz testing for GoModParser

[mastersans]

fixes #3325

Added a fuzz testing for GoModParser(go.mod), made .proto file based on go.mod file reference ,
Although the GoParser (go.py) mainly parses for requirements('require'), but I included 'replace' and 'exclude' also.
I have tested the fuzzer in a container, also attached the screenshot below:

This looks really promising! I'm going to go ahead and approve the CI tests to run, and I'll be back for a more careful review after that's done.

Looks like we've got some linters failing, but thankfully those should be pretty easy to fix.

The contributor guide has some info on what the linters are used for and how to set them up:
https://github.com/intel/cve-bin-tool/blob/main/CONTRIBUTING.md#running-linters

The ones that are failing can probably be auto-fixed using the same tools. Once you've got them installed, try running

isort fuzz/fuzz_go.py

and those should fix the sorting issues, then something similar with black (which should also fix the flake8 issue) and pyupgrade. Update the pull request with the new files.

It does look like it's complaining about the generated file (which we should probably ahve those linters ignore) but go ahead and just run the fixes on it for now even though it says not to edit it. I'll open a separate issue to see if our config needs updating so stuff in fuzz/generated/ is ignored correctly in the future, but it's easier to just check in a slightly cleaned up file for this PR.

I ran the linters on the both fuzz_go.py and go_mod_pb2.py, both had some issues which are fixed also the pre-commit shows passed before commiting, I should have used it earlier.

Time to get this merged. Thank you again for working on this!
