Tools: Test, Tune: Improve Matlab scripts for EQ testing 

The test scripts missed test component keyword change from e.g.
eqiir to eq-iir. Due to this the process_test() failed for IIR and
FIR for gain and frequency response due to wrong result expect.

The expected result is retrieved with the blob decode function. It
can be also used manually to check the filters defined in the
blob. The help texts in the decode functions needed fix. Also some
usage examples were added.
