Report decoding inconsistency between app and apple_cryptography.py

[adntaha]

Hi,

I'm trying to increase my understanding of this codebase, and while doing so, I stumbled upon the following inconsistency. In the following snippet, i in lowercase is for a signed int.

macless-haystack/endpoint/register/apple_cryptography.py

Lines 30 to 32 in 0bda271

	def decode_tag(data):
	latitude = struct.unpack(">i", data[0:4])[0] / 10000000.0
	longitude = struct.unpack(">i", data[4:8])[0] / 10000000.0

Meanwhile, in the web app, the same bytes get decoded as an Uint:

macless-haystack/macless_haystack/lib/findMy/decrypt_reports.dart

Lines 73 to 76 in 0bda271

	static FindMyLocationReport _decodePayload(
	Uint8List payload, FindMyReport report) {
	final latitude = payload.buffer.asByteData(0, 4).getUint32(0, Endian.big);
	final longitude = payload.buffer.asByteData(4, 4).getUint32(0, Endian.big);

So, I don't get it. Are both of these approaches valid because lat/long don't ever get high enough, or is one of these going to lead to a bug?

Thanks a lot!
