Allow axes to be constructed by namedtuple syntax in Map

[asinghvi17]

Allows

b = Rect2f(-20.0, -20.0, 40.0, 40.0)
m = Tyler.Map(b, provider=OpenStreetMap(), axis = (; type = GeoAxis))

f = Figure()
m = Tyler.Map(b, provider = OpenStreetMap(), figure = f[1, 2])

LGTM, I wanted this the other day instead of setting up a GeoAxis manually

One test is failing 😔

This needs a rebase, let's not merge yet

[asinghvi17]

Ok...I have no clue what's going on with this segfault :(

[asinghvi17]

We could also add an LMap, as a way to switch away from requiring control over the figure. But that's out of scope for this release (v0.2.1).

It looks like the segfault is a known error in the interaction between julia and curl:

curl/curl#14860

so I think we can merge as is. Doc build failed for external reasons (I think)...
