`getCoverage` needs to download in tempdir instead of current wd, when no filename is provider

The documentation gives the impression that files are written out only when argument filename is used.
Line 115 in 4887477
However getCoverage() always downloads and writes out a file, regardless of whether a filename has been provided. This ends up polluting the working directory (e,g my EMODnetWCS package directory as well as the testthat directory within is constantly filling up with files from development and running tests.
If this is a default behaviour of terra should it not download to a temp directory instead if filename is not provided? At the very least the documentation should reflect this fact.
