v2 (#108)

### Update versions
- auto:
3f417566b0

### Breaking changes:
* renamed `automatic-1111` service to `auto`
* the `cache` folder is now deprecated, replaced with `data` (see
migration guide below)
* `embeddings` folder has been moved to `data/embeddings`
* use GFPGAN 1.4

### Migration Guide

Note: in theory, running the command 
```
docker compose --profile download up --build
```
is all you need to use the new version, however, this means you will
also have to download everything again. A new script is available under
`scripts/migratev1tov2.sh` that will copy models to the new structure
and should get you most of the way, run
```bash
./scripts/migratev1tov2.sh
```
or you can manually inspect the script and copy the files

After that, run
```
docker compose --profile download up --build
```
to validate everything.
