BUG: Handle missing Analyze 7.5 flipped directions

We have a customer with an Analyze file that is
'flipped'.  There is currently a comment saying:
"according to analyze documents, you don't see
flipped orientation in the wild".
Well, we just did. :)

Fixed by adding the missing cases, specifically:
 a75_transverse_flipped:
 a75_sagittal_flipped:
 a75_coronal_flipped:

Fixed by my colleague Mathieu Coursolle.
