Suggestion for resolver improvement

[novitae]

In order to improve the capabilities of the resolver, it might be interesting to add the source of the value. E.g:

def resolver(t, source):
    print(t, source)
    return barely_json.default_resolver(t, source)

barely_json.parse("{hello: world}", resolver=resolver)
barely_json.parse("[hi, {hello: world}]", resolver=resolver)

hello key
world value
hi item
hello key
world value
