customize snapshot_path

[15r10nk]

add more arguments to the customize hook which give the user some information about the location in the snapshot, which is useful in cases like this:

from inline_snapshot import snapshot

def request(user):
    return {"user":user,"age": len(user)*2}

def test():
    user="Tom"    
    assert request(user) == snapshot({"user":user,"age":6})

where the key of the dict entry can be used to find the correct variable.

def customize(value, snapshot_path):
    ...

snapshot_path is a list of locations in the snapshot in this case [DictValue(key="user")], but in can contain other entries like ListIndex or CallArgument.
