[C++][Python] strptime fails to parse subsecond timestamps

Joris Van den Bossche / @jorisvandenbossche:
@TarasKuzyo very late reply, but so such fractional seconds are not yet supported in strptime at the moment. This is also described in ARROW-15883 in more detail, so going to close this issue as a duplicate of that one.
