Title: RFC: lapack interface: Change String to Char/Uint8 for single-char arguments

I noticed that we were using Strings all over the place in the lapack interface while only the first character is needed, so I changed the API to us Chars and/or Uint8s instead. Just wanted to make sure this is ok with everybody before committing (particularly @dmbates and @ViralBShah).
