  • fix bug: pioasm was spilling bit 5 of arg2 into arg1
  • make pio_add_program flip bit 5 of a WAIT GPIO instruction if gpio_base is 16

Note: pioasm will encode only the bits 4-0 of arg2 (the GPIO number), however it does indicate whether 0-15 means 0-15 or 32-47. This can only be fixed up when loading the program, and indeed once the GPIO base is known. pio_can_add_program and friends already detected the cases where this was impossible

Ok. After staring at this for awhile it looks good. We really should have an example of using this. Any suggestions?
