= nano_wii support
- orientation 90deg clockwise from arrow is front (towards rx pins)
- need to fix cppm and led
- VR, DIP switches missing. so, need stick config
= fix up cppm and led on nanowii
- cppm on PE6 / D7 / THR_IN / INT6
- common cppm isr handler (nanowii uses INT6_vect, rx3s uses PCINT0_vect)
- led on PD5

= read_switches() should use PINx instead of PORTx to read input

= basic stick config code
= used common led register based access method for all devices (no mixing digitalwrite with portx |= x)

= updated nanowii pin mapping (in particular rx channels)

= stick_config updates (still not ready)
= nanowii
- enabled AUX2_IN on PE6
- renumbered servo out pins (not final yet)
Revert "= used common led register based access method for all devices (no mixing digitalwrite with portx |= x)"

This reverts commit 59f88846b205ab84027793f538c70f4a4cff00ee.

restored all the hex files i accidentally deleted :)
