[Ovmsdev] Adding support for eGolf

Hello! I recently bought a 2019 eGolf and I'm interested in getting support for it in the project. Some folks on the OVMS Discord server have code that appears to work and I've volunteered to try to merge it. I've yet to run the code myself (I'm still waiting on a harness), but I thought I'd ask what the process might look like. Do you want small pull requests where each one covers a single, small feature? Are you okay with merging everything at once, provided it doesn't break other vehicles? Erick
