Description

Implement the decoding for Philips Hadamard matrix.
Philips data should be a standard Hadamard working with the normal code. So I have only cleaned and optimized the code.

Requirements

-> inside xASL_quant_HadamardDecoding function:

• clean and optimize the previous code
• add default Philips decoding matrix
• multiply the decoding matrix per -1 if x.Q.Vendor is Philips

-> inside xASL_wrp_ResampleASL function:

• after decoding, average across repetiitons (as we already do for multiPLD data) - save as PWI4D.nii (=keep as is).
• before averaging across PLDs, we take only the first TE of each PLD and we average across PLDs - save that additionally as PWI.nii (to be added similar like for multiPLD).

Release notes

Clear the Hadamard decoding code. Add decoding matrix for Philips
