Add force to RasterCreator

[felixcremer]

This should fix #1047 by adding the force to the RasterCreator struct and so to be used as a keyword to rasterize.

I added the changes to test_utils, because I ran into test failures because I had a manually created tempname tif file in my temp folder which interfered with the RasterSeries tests. This adds a temporary dir so that every use of the temporary raster construction uses a separate folder.

Locally I get some seemingly unrelated failures due to some RASTERDATASOURCE variable not set in ENV. I don't understand why this failure comes up with these changes.

We need that for rasterdatasources tests, but it is set in ci.yml, so not really a failure

[felixcremer]

Could we set this somehow also locally. Because it is annoying to have local tests failures due to that. Could we instead of setting them via a yml as ENV["RASTERDATASOURCES_PATH"] from within julia in the tests that need it?
