This is small fix only for tokha instance so mistakely raised PR here going to close it

Each TMS is unique - there is no agreed upon standard if the XY should be reversed or not, so we can't have a general rule in place.

Either:

• We extract from the URL placeholders provided and set automatically.
• Its user configurable.
• We have something more complex, like attempt a download for both and see which one succeeds, then continue.

Actually no need to address this though, as long as its fixed for Tokha 👍

basemapper will be replaced with other options in the near future!
