Add support for MapTiler SDK

[petr-hajek]

Description

As a user of MapTiler SDK & MapTiler maps I'd like an easy way how to compare also MapTiler maps.
With this PR I can add MapTiler API key to the config (similar to MapBox). I can also use MapTiler SDK as a renderer (it's almost the same like MapLibre).

I removed the duplicate code in Map.svelte

QA steps

Probably some basic regression of MapLibre & MapBox but should not be affected

@petr-hajek Thanks for this! We'll be taking a look at this soon.

It's my first PR into this project and for full transparency, MapTiler is my client so I am open to any feedback. Thanks a lot. Anyway, this is a great tool!

Looking good here!

I left a long explainer for this, but basically I think we may need to switch the order of our || conditional here to be style || url as opposed to how it is now.

We'll also want to QA that change and make sure there's no weird side effects.

Sorry for not responding. I was loaded with other things, but I'll try get back to this soon, thanks for the feedback.

Sorry it took me so long.

I moved the url normalization to a separate file and apply it in the GlMap component as well. It now works with Maplibre and Mapbox renderer as well.
