LZ4_compressBound() :
Provides the maximum size that LZ4 may output in a "worst case" scenario (input data not compressible)
primarily useful for memory allocation of output buffer.
+ inline function is recommended for the general case,
+ but macro is also provided when results need to be evaluated at compile time (such as table size allocation).
