[MapProxy] transparent layers get an opaque background after merging

Thanks for your idea, I thought "request_format" is for WMS only.

But it didn't work:

  format: image/png
  request_format: image/png

This also would work in "caches" only, not in "layers" (where merging is
also allowed).

It really might be a Pillow problem. I'll try to extract the images from
the mbtiles and analyze them.
