This reverts commit ae77d5cd54e1f43d390fb70c4da38a95ac34f8da.

* need to check WMI

* TODO: test WMI

* test wmi

* radar FW sanity check

* fix test

* fixes from merge

fixes from merge

* whoops

* fix static analysis!

* do match_fw_to_car

match_fw_to_car takes vin

* makes sense to keep it one function, and we can return exact or fuzzy!

* clean up

* kinda pointless

* fix more tests

* back to function being only fuzzy

* revert test_fw_fingerprint

* revert test_fw_fingerprint

* simplify

* clean up/fixes

* rename test

* less duplicatey WMI descriptions

* fix

* convert to enum

* I am confident about these WMIs

* these are also good

* we support 5N AUS/NZ and NAR (North American) AX Tiguans

fixes

* Tiguan also Mexico

* only one user for caddy

* got from the test route

* check that the gateway type matches the platform (each platform has 1 or 2 types)

* ~gateway~ -> exact FW match

* remove re

* ensure WMIs are set

* actually no reason to delete

* move comment up to the platform config

* proper wmis typing

* spacing

* flip
