feat: Move TripsLayer and ArcLayer out of experimental (#983)

Sadly this diff is kinda big from moving things around 🙈 

### Change list

- Split the big `layers.py` file into separate files with one layer per
file
- Split the big `traits.py` file into separate files
- Move `TripsLayer` and `ArcLayer` out of the `experimental` module

Closes #938
