increase parallel block for LZ4 data compression

[rourabpaul1986]

Hi I was using https://github.com/Xilinx/Vitis_Libraries/blob/master/data_compression/L2/demos/lz4_streaming/

I found this design has PARALLEL_BLOCK value of 8 (default). It also mentioned "Overall throughput can still be increased with multiple compute units."

Could you please inform me which file I should modify to increase the number of PARALLEL_BLOCK in each computation unit for better throughput?

I have already tried two approaches

1. I have found line 140 and and line 146 in [Makefile] mentioned DPARALLEL_BLOCK=8. I changed those DPARALLEL_BLOCK, but did not get the result.

2. I found #define PARALLEL_BLOCK 8 in the line 43 of lz4_compress_stream.hpp. I have changed this value but did not work for me
