Fix stack overflow when decoding deeply nested structures like arrays and maps

[MarshalX]

fixes #9

It uses 2 approaches. First for Python 3.8 and second for Python 3.9+. The first one hard limits recursion to 1k (same as python by default). The second one respects sys.setrecursionlimit. decode_dag_cbor function could now raise RecursionError

CI fails because of temporary disabled endpoint by bsky team to deal with network load
