* chore: cleanup LU(W)string writing and add methods for reading remove redunent "packet" from packet reading helpers move write header to bitstreamutils since it's not packet related add tests for reading/writing LU(W)Strings * remove un-needed function defintions in header * make reading and writing more efficient * p p * quotes * remove unneeded default --------- Co-authored-by: David Markowitz <39972741+EmosewaMC@users.noreply.github.com>
