Implement tiles for Azure Maps

[kopytjuk]

Code:

import matplotlib.pyplot as plt
import cartopy.crs as ccrs

from cartopy.io.img_tiles import AzureMapsTiles

tiler = AzureMapsTiles("your-key", tileset_id="microsoft.base.road")
mercator = tiler.crs

fig = plt.figure()
ax = fig.add_subplot(1, 1, 1, projection=mercator)
ax.set_extent([	9.206600, 9.240600, 49.135002, 49.1552], crs=ccrs.Geodetic())

ax.add_image(tiler, 15)

ax.plot([9.219108094488016], [49.141744935977776], "r+", label="Kilianskirche", transform=ccrs.Geodetic())

ax.set_title("Heilbronn, Germany\nwith microsoft.base.road tileset")
ax.legend()

plt.show()

Rationale

Easy access to Azure Maps tile images for plotting maps.

Implications

An additional CI-variable AZURE_MAPS_SUBSCRIPTION_KEY has to be set for tests.
