[BUG]ionosphere temp file not found during dim check

[rzinke]

Describe the bug
ariaTSsetup.py is throwing an error when extracting ionosphere layers. It appears to be failing while checking for layers of a previous product that does not (or no longer) exists. The issue is possibly related to issue #420 and PR 421.

To Reproduce
Steps to reproduce the behavior:

1. Download three products

ariaDownload.py -t 71 -b '37.5 39.5 -118.5 -114.5' -s 20200515 -e 20200601

2. Command used

ariaTSsetup.py -f "./products/*.nc" -l ionosphere

3. Error Output

Expected behavior
Extraction of stack/ionoStack.vrt as demonstrated in the ARIA-tools-docs notebook. I am not sure why it worked there but not in my case, as the notebook was updated more recently than PR 421.

GDAL looks for a temp_xxxx file on which cropped and resampled datasets are built, however, the temp files are deleted. Extracting to disk (for both multiple products and single product) fixes this issue.

Suggested fix in PR #448
