plotly.js Enable "TMS" tile layer scheme as overlay in scattermapbox.

There are two different ways of defining xyz tile layers for map visualisation. They are differing in the orientation of the naming of the y coordinate: The TMS specification orders from Bottom Left and the Google/OpenStreetmap (WMS, 'slippy') specification orders from Top Left. So the y naming is inverted.

Here you can find the required mapbox gl entry point: Vector->Scheme

This issue https://github.com/plotly/plotly.py/issues/1610 and this thread https://github.com/plotly/plotly.py/issues/2272 relates to this problem.

We'd be happy to integrate a PR for this but as far as I know no one is actively working on it :)

Replacing the hardcoded "xyz" with "tms" in plotly-2.8.3.js allows using tms tiles just fine. There is this piece of code which handles the translation of the y coordinate: scheme === 'tms' ? Math.pow(2, this.z) - this.y - 1 : this.y.

The fix would be trivial, just allow users to specify "scheme" and pass it further where currently "xyz" is hardcoded.
