This is the core compression module which seperates the input stream into two output streams, one literal stream and other offset stream, then lz4 encoding is done.
Parameters:
| PARALLEL_UNITS | number of parallel units |
| MAX_LIT_COUNT | encoded literal length count |
| inStream | Input data stream |
| outStream | Output data stream |
| max_lit_limit | Size for compressed stream |
| input_size | Size of input data |
| endOfStream | Stream indicating that all data is processed or not |
| compressdSizeStream | Gives the compressed size for each 64K block |
| index | index value |
