Support for Block Encoding and Decoding

[ztnel]

Description

Block encoding refers to the concept of receiving a stream of data in excess of the configured block size. For example, an encoder configured with a block size of a byte can receive a stream of data larger than a byte and divide the byte into sub-blocks which I will refer to as frames (for legacy reasons). Therefore a stream of hf encoded in utf-8 will be subdivided into byte \x68 and byte \x66 which will be represented as 2 subsequent frames.
