Beam’s C implementation is done

After quite a bit of time, I’ve finally finished the C implementation for Beam as well. This is more portable for systems that do not have Rust, though I doubt that matters since LaTeX is quite hefty as well.

In any case, it was mostly for my own learning experience. And learn I did:

• File i/o
• Used malloc() and free(). Also learned about realloc(), though I intentionally did not fix segfaulting for slides/presentations that were too long (since long presentations are bad)- Learned about structs/enums/unions in C (and how to make a tagged union), though I never ended up using them
• The equivalent of str.split() in pretty much any other language
• Wrote a Makefile for the first time, learning about .PHONY and the all convention, including files like config.mk, and the ${DESTDIR} variable.

And this is only a subset of what I applied in the code. Since it’s my first program in C, the code probably sucks ass. If you want to make sure something works I’d use the Rust implementation because I don’t suck as badly at Rust, this was just an educational exercise for me.
