Incorporate wdx_ziptype changes (fix for Poco::Zlib: Unexpected exceptions and others)

[tbeu]

Recently, I did a couple of changes to Poco::Zlib in my copy to not throw

• on parsing ZIP archives containing duplicate entries
• on parsing ZIP archives with compression methods > 10
• on parsing ZIP archives with an unexpected data descriptor

Feel free to adopt upstream as you like.

@tbeu, thank you. Can you create a pull request, please?

tbeu wdx_ziptype repository contains fixes that would be worth incorporating to main repository.

Note, that I did a several shortcuts which should not go to the upstream repo, Especially I did not find a good enough solution for duplicate entries.

I believe that the test files of https://gitlab.com/tbeu/wdx_ziptype/-/tree/master/test/data are also of general interest.
