make it work with WGLMakie

[lazarusA]

In the current version, doing:

using WGLMakie
using Tyler
tyler = Tyler.Map(Rect2f(-0.0921, 51.5, 0.04, 0.025))

shows the map and getting new tiles is possible. However, some errors are alive 😄

weird: this only show up once (the first time I ran the lines).
