Find Event Instruction Byte Offset

#   ROUTINE: FIND EVENT INSTRUCTION BYTE OFFSET
#       Finds the next byte offset in the current event, from the specified starting point, of the specified instruction ID.
#       Parameters:
#           r4 = (p_startingByteOffset) Byte offset to start at
#           r5 = (p_instructionID)      Instruction ID to find the byte offset for
