Support for custom Imagery in TMS format (flipped y coordinate) #107

Go Map!! has supported custom imagery for a while. I create a tile server with high resolution orthophotos for my hometown that are unavailable anywhere else. Unfortunately, I created the tiles using Mapbox Tilemill in TMS format, which uses a flipped "y" coordinate. Both iD and JOSM support TMS format by using the {-y} syntax in the custom URL. I tried the same URL syntax in Go Map!! but it does not work. I really hope you could add this functionality, as Bing imagery is misaligned and blurry in my hometown of San Juan, Puerto Rico.

Explanation of how the flipped y coordinate works

In the meanwhile, you can set up mapproxy to serve them in a format GoMap supports.
