PinChangeInterrupt library debug

This library already supports a local debug macro in `PinChangeInterruptSettings.h`:

- `__PCINT_DEBUG__` (default 0) controls `PCINT_DEBUG_PRINT(...)` which prints
with `Serial.println(F("..."))` when enabled.

Examples to enable:
- platformio.ini (per-environment):

[env:program_DiamexISP]
build_flags = -D__PCINT_DEBUG__=1

- Or define before including the library headers:

#define __PCINT_DEBUG__ 1
#include <PinChangeInterrupt.h>

Notes:
- Debug prints use `F("string")` to keep strings in flash (saves RAM).
- When disabled, `PCINT_DEBUG_PRINT(...)` expands to nothing.
