chore: cleanup LU(W)string writing (#1188)

Browse Source 
* 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
