I didn't study how t at h server works so my idea might be nonsense.
Anyway, if main problem is file unpacking and metadata updating, then
what about uploading tileset in some simpler file format than zip a
keeping full tileset as one file?

Fileformat will be something very simple, like:
index to tile1, index to tile2, ... tile1, tile2...

It will also allow to save blank tiles, index = 0 => blank tile, land;
index = 1 => blank tile, sea.
