I only use here a small part of putbitcontext, and in an "unsafe" mode (the
buffer of the prores aw encoder is big enough to not check it, and write 64
bits during the flush even if less can be use (to keep code more simple))

Maybe can be used later as a start to write a more general PutBitContext
with 64 bits bit_buf, for use in various encoders.
