compressor: if blosc is compiled with all compression libraries, default = memcpy
available compressors: zlib, lz4, lz4hc, snappy, zstd, blosclz, memcpy (plain data copy)
lvl: valid range [1;9], lower number means faster compression but lower compression ratio, default
= 1 (fast)
threads: valid range [1;number of native threads], default = 1
threshold: in byte, valid range [1;2^31], default = 128
