papi: vpp_serializer.py - replace slow bytes() with fast bytearray()
https://docs.python.org/3/library/stdtypes.html "if concatenating bytes objects, you can similarly use bytes.join() or io.BytesIO, or you can do in-place concatenation with a bytearray object. bytearray objects are mutable and have an efficient overallocation mechanism" Type: improvement Signed-off-by: Viktor Velichkin <avisom@yandex.ru> Change-Id: Id20d337f909cce83fcd9e08e8049bb0bf5970fbc
