New Package: tochemfig.el - Make Emacs write chemfig code from molfile or SMILES.

TIL `mol2chemfig` is even a thing. `chemfig` is too tedious to write by hand.

Yeah, I agree and that's why I searched for a way to import molecules in SMILES and I discovered mol2chemfig. I was like "well, I could script this one" to run everything from the Emacs; and finally I ended building up all the package lol
