Update protocol for public type hints
This issue will update the protocol class used for the public type hints (`Coord`, `Data`, ...) so that it accepts [collection](https://docs.python.org/3/library/collections.abc.html#collections.abc.Collection)-typed objects. Note that this update will not affect any runtime behavior exposed to users, but change (improve) the behavior of static type check.
