Get known skillsets

#   ROUTINE: GET KNOWN SKILLSETS
#       Gets the skillsets known by the specified formation unit.
#       Parameters:
#           r4 = (formationUnitIndex) Formation unit index
#           r5 = (outputArray) Array to write result into
#       Returns:
#           r2 = Number of skillsets
