parsers: factor out most of asciilower into an internal function

We're going to reuse this in upcoming patches.

The change to Py_ssize_t is necessary because parsers.c doesn't define
PY_SSIZE_T_CLEAN. That macro changes the behavior of PyArg_ParseTuple but not
PyBytes_GET_SIZE.

# Usage:
#   seq STOP              [1, STOP] stepping by 1
#   seq START STOP        [START, STOP] stepping by 1
#   seq START STEP STOP   [START, STOP] stepping by STEP

stop = int(sys.argv[-1]) + 1
