ReadStringBytes allocates #145
Description
Hello,
thank you very much for your work. it works very nicely.
one thing i noticed though,
in my app, github.com/tinylib/msgp/msgp.ReadStringBytes is the largest allocator of objects (note: by far not the largest cause of memory usage, so it's just that it allocates a lot, but often not much each time)
is there anything that can be done? I'm using the UnMarshal method
(pprof) list ReadStringBytes
