LibGfx: Allow creating Bitmaps from ReadonlyBytes objects

Browse source 
The existing try_create_from_serialized_byte_buffer function accepts a
ByteBuffer, but in reality it requires only a ReadonlyBytes, since
internally the only thing it does is calling buffer.bytes(). There is
thus no reason to have a function that simply accepts ReadonlyBytes, and
implement the former in terms of the newer.
