  • mixer_{multicopter,helicopter}: add buffer size check
  • io_timer: fix potential invalid memory access

See individual commits for details.

Fixes a potential buffer overflow if an MC/helicopter mixer is used that
exceeds the number of physical pins.
This is not a useful/flyable configuration, but the system still should
not crash.
