 LZ4 is an LZ77-type compressor with a fixed, byte-oriented encoding.
 The most important design principle behind LZ4 is simplicity.
 It helps to create an easy to read and maintain source code.
-It also helps later on for optimisations, compactness, and speed.

 The latter is assumed to be handled by other parts of the system.

 not how the LZ4 compressor nor decompressor actually work.
 The correctness of the decompressor should not depend
 on implementation details of the compressor, and vice versa.

 An LZ4 compressed block is composed of sequences.
 Schematically, a sequence is a suite of literals, followed by a match copy.

 There is no assumption nor limits to the way the compressor
 searches and selects matches within the source data block.
 It could be a fast scan, a multi-probe, a full search using BST,
