python3-lgpio: Add recipe

Add recipe for release 0.2.2.0: - Changes forced by the adoption of a different timestamp clock in gpiochip API 2. - The gpiochip changes broke the operation of GPIO debounce and watchdogs. Signed-off-by: Leon Anavi <leon.anavi@konsulko.com>

+Subject: [PATCH] PY_LGPIO/lgpio.i: Replace undefined functions
+
+Replace functions PyInt_Check, PyInt_AsLong, PyInt_FromLong and
+PyString_FromString for Python3 because SWIG dropped its Python
+2/3 compat shim in version 4.1. Fixes:
+
+error: implicit declaration of function 'PyInt_FromLong';
+did you mean 'PyLong_FromLong'? [-Wimplicit-function-declaration]
+
+error: implicit declaration of function 'PyInt_Check';
+did you mean 'PySet_Check'? [-Wimplicit-function-declaration]
+
+error: implicit declaration of function 'PyInt_AsLong';
+did you mean 'PyLong_AsLong'? [-Wimplicit-function-declaration]
+
+Upstream-Status: Submitted [https://github.com/joan2937/lg/pull/46]
