  11 /// NihAV has its own MD5 hasher that calculates hash for input frame in a deterministic way (i.e. no endianness issues) and it outputs hash as `[u32; 4]`. During testing the resulting hash will be printed out so when the test fails you can find what was the calculated hash (and use it as a reference if you are implementing a new test).
