Make it work with GeoAxis

[felixcremer]

It would be nice if it would be possible to use a GeoAxis from GeoMakie in Tyler.Map.
When I am trying it, I get the following error:

fig = Figure()
julia> ax = GeoAxis(fig[1,1], dest="+proj=webmerc +datum=WGS84")
GeoAxis()
julia> mgeo = Tyler.Map(ext, m.crs, figure=fig,axis=ax)

I got around this issue by setting the source keyword for the GeoAxis to also use webmerc as the source projection.
I managed to plot something but it seems that it is only fetching a few tiles and this might be a projection issue.

[felixcremer]

There is some strange interaction between GeoMakie and Tyler. When I construct the Map object it fetches some tiles that I would also expect to be fetched but they are not displayed on the Axis and as soon as I try to interact with the data it fetches only one tile that is on zoomlevel one and at (0,0) and therefore only shows the ocean.
