Standard hash to generate index of contract being snapshotted

[anomit]

Is your feature request related to a problem?
The current selection of the indexes of the pair contracts to snapshot out of the entire list available to the Uniswap V2 data market uses a non-standard hash function that may be unavailable or differ in its output when porting to other languages, frameworks or runtimes.

	def _gen_pair_idx_to_compute(self, msg_obj: SnapshotProcessMessage):
	monitored_pairs = module_settings.initial_pairs
	current_epoch = msg_obj.epochId
	snapshotter_hash = hash(int(settings.instance_id.lower(), 16))
	current_day = msg_obj.day
	return (current_epoch + snapshotter_hash + settings.slot_id + current_day) % len(monitored_pairs)
