Description

Some small changes to improve the FSL detection and execution:

1. The settings are x.FSLdir but x.RootFSLDir - easy to make a typo there - change to Dir or dir everywhere 👍🏼
2. If we are below FSL version 6.0, issue a warning 👍🏼
3. Change BASIL quantification x.bUseBasilQuantification to true in 1 TestDataSet case 👍🏼
4. xASL_wrp_Quantify - line 78 add a warning for x.bUseBasilQuantification so that's clear that a BASIL PWI4D.nii 👍🏼

By Henk: I removed the RootFSLdir comments, this should always be the same as FSLdir unless you use WSL.
By Henk: PWI4D.niiis only deleted at ASL module step 9: xASL_wrp_VisualQC_ASL
By Henk: "bUseBasilQuantification": 1 is now added to Philips_2DEPI_Lesion_NoFLAIR_NoM0_HiQ & Philips_3DGRASE_FLAIR_M0_2ndRun_HiQ

Release notes

• Minor fix in setting up FSL, issuing a warning when FSL version <6, and testing bUseBasilQuantification in both a 2D and 3D ASL dataset
