Fixes to external phase encoding table handling
This fixes residual issues with the handling of phase encoding data (as suspected following #3122 and reported in #3127).

The issue was that when combining data with more complex phase encoding contrast than just reversal, results from dwifslpreproc were OK if the NIfTI was left-handed but erroneous if right-handed. This has been corrected and verified with extensive testing, and everything should now be handled correctly.
Generate correct applytopup_config.txt
This provides a workaround for #3122, which relates to the phase encoding table handling issues mentioned above.
dwifslpreproc & mrcat: strides fix
Fixed issue with improper correction of susceptibility distortions in ddwifslpreproc, caused by trying to use the phase encoding directions k and k- when invoking applytopup, which is presumably deemed unacceptable internally by applytopup.
