quantization api name consistency #375
Description
having the string to get a type of quantization and the constructor for that quantization as different text is super annoying.

quantize(model, int4wo()) ->works.......while quantize(model, "int4wo") -> error, wrong name
its a pain to have to remember which is which here, either both should work for the string or consolidate on a single one.
for that matter these also don't match
