filter() throws NotImplementedError when there is a filter expression in jsonpath

[WilliamYuhangLee]

The filter() function does not work when there is a filter expression in the jsonpath, and it throws a NotImplementedError. Code to duplicate this error:

obj = {
    "a": [
        {"b": "X"},
        {"b": "Y"}
    ]
}

jsonpath = parse("$.a[?(@.b==X)]")

matches = jsonpath.find(obj)
print(matches[0].value)
>>> {'b': 'X'}  # find() returns correct value

result = jsonpath.filter(lambda x: True, obj)
>>> NotImplementedError  # filter() throws error
