Get Inner Text (WORLD.BIN)

#   ROUTINE: GET INNER TEXT (WORLD.BIN)
#       Splits the input text on a sentinel value for inner text (0xFE or 0xFF), and returns a pointer to the inner text with the specified index.
#       This is the same as the Get Inner Text routine in BATTLE.BIN.
#       Parameters:
#           r4 = (inputText) Input text
#           r5 = (innerTextIndex) Index of inner text
#       Returns:
#           r2 = Text character pointer to inner text with specified index
