Blob — the sourced bytes as a new blob
This method reads the specified number of bytes from the blob and returns them as a new blob.
The new blob’s bytes are taken from the current read/write pointer onwards. The pointer can be determined using the tell() method and set using the seek() method.
Only those bytes up to the end the source blob are read; if the call asks for 256 bytes but the read/write pointer is 128 bytes from the end, the new blob will be 128 bytes long.
The size of the new blob can be verified using the len() method.
