* Implement IGNORE_MOD_TAP_INTERRUPT_PER_KEY
- Add configurable option IGNORE_MOD_TAP_INTERRUPT_PER_KEY
- Add function get_ignore_mod_tap_interrupt iff the option is enabled
Unless IGNORE_MOD_TAP_INTERRUPT_PER_KEY is defined, this patch does not affect the resulting binary.
* Add documentation for IGNORE_MOD_TAP_INTERRUPT_PER_KEY
