[BUG] `{d}` `urlTemplate` placeholder improperly converted to string on non-web platforms

[geoextra]

What is the bug?

When using the {d} in the urlTemplate (introduced in #1665) it defaults to a float value which gets converted to string (e.g. 256.0). This is obviously not supported by many tile providers.

How can we reproduce it?

Use the following option: urlTemplate: 'https://api.mapbox.com/styles/v1/mapbox/streets-v12/tiles/{d}/{z}/{x}/{y}{r}?access_token=$mapboxPublicToken'. The tile server will respond with 422 status codes. Problem doesn't occur on web due to differences in types and therefore toString().

Do you have a potential solution?

I don't see why the resolution needs to be a double, maybe it can be changed to an integer type.
