fix: Make extraction work for MSI files when unzip and 7zip installed

[captainreality]

This commit fixes an issue where if both unzip and 7zip were installed, MSI file extraction failed because unzip was attempted first, and failed.

Now in the case where both are installed, unzip is tried, and if that fails, then 7zip is tried.

Thanks, this looks promising. I've set the tests to run and I'll be back to do more careful code review when they're passing.

Hi @terriko, thanks for running tests. I'm a bit confused. When I run the failing tests locally (all except the Windows long tests), I get no errors if I run the tests individually. Specifically, these tests are test_html.py and test_csv2cve.py.

However, if I run the full test suite, test_csv2cve.py is failing. However, it's failing on a different line of code to the failure that occurred in the test suite run on the GitHub workflow. This is really strange.

I've attached two files; one with the output when the two tests pass when I run them individually, and one with the output when test_csv2cve fails.

I don't know if you've seen this before. It looks suspiciously like some kind of environment difference.
csv2cve_error.txt
test-out.txt

Anyhow, thanks for taking a look at this.

Edit... also note that when I ran the tests individually, I ran them with pytest, and also tried python -m pytest. It made no difference.
