Title: Make the bibtex key mapping optional by additional argument in parser 

Making the keys sanitising/homogenising optional by adding additional parameter to `BibTexParser`. I'd like to be able to read bibtex file, parse it and write it back to file without any changes. I'm happy for keys to be converted to lowercase though, in case they weren't.
