buffer: Support length == 0 for ply_buffer_append_bytes
Right now callers of ply_buffer_append_bytes have to be
very careful to make sure the data they're appending is
non-zero in length. This is kind of inconvenient, since
it's not unusual for data to come in that's zero bytes
long.
For simplicity, this commit just makes
ply_buffer_append_bytes support that use case.
