Support for EU Hyundai

[schmidtwmark]

BetterBlueKit does not support EU Hyundai vehicles. Steps to enable it:

1. Create a HyundaiEU.swift file with a class that overrides HyundaiAPIEndpointProviderBase
2. Use a proxy to capture login / fetch vehicle / command flow from the MyHyundai app
3. Override endpoint methods to match captured logs
4. Update BBCLI to create your endpoint provider
5. Run swift run bbcli -u [username] -p [password] -b hyundai -r EU
