Add option to ignore specific files completely from optimization

[MCMDEV]

Related problem or need

I'd like to have some files that are part of the resourcepack not be optimized/processed but still be added.

Proposed solution

A boolean per-file option

Alternative solutions

Not supporting this

Additional context

I'd like this because I found out that NegativeSpaceFont is incompatible with PackSquash. There is a PR at NegativeSpaceFont to address this (AmberWat/NegativeSpaceFont#11). Nevertheless, I think having the option to skip out on processing could help mitigate similar issues.

Frankly, I'm reluctant to add new options solely as workarounds for issues in specific packs. Even when they highlight improvable behavior or missing features in PackSquash, I find that the proper solution to that tends to be either improving such behavior or implementing such missing features, not skipping optimization altogether. For AmberWat's negative space font pack, it's better to heed the lint from PackSquash and fix the problem at the source by using interoperable number ranges, as I did in the PR you referenced, where I explained my technical reasoning for that opinion in more detail.

That being said, another user presented a compelling reason for having this feature that goes beyond working around pack issues or limitations in PackSquash, so I'm open to considering it. Still, as a PSA to everyone, please try to avoid using it simply to quietly work around individual pack issues... Imagine the collective hours of time wasted by humanity if everyone added extra options to their own particular PackSquash options file rather than even trying to propose fixing issues at the source for everyone to enjoy, no matter their particular software stack 😅

Thanks a lot for the feedback though, even though I don't agree with the proposed way to solve it I think it's a valuable experience to share and keep in mind.
