------------------------------------------------------------
Regression tests in prep for 1.17 found a blocker caused by an incomplete fix
to this issue. We need to add quite a few more specializations of zip and tar
to check for and avoid overwriting of mime types to zip. Lots of files that
were identified as kmz, tika-ooxml, etc in 1.16 are now being identified as
"zip" during the parse in 1.17-SNAPSHOT.
Current patch includes list semi-manually, which I abhor, but I added a test to
make sure that PackageParser's list of specialization stays current with
TikaConfig's default config.
After 1.17 is released, we can either work towards getting rid of serialization
of parsers in ForkParser and/or making TikaConfig serializable. Until we do
that, I don't see an elegant solution.

> The mediaTypeRegistry handling code in parse() of PackageParser seems cause
> the problem due to ForkParser cannot properly construct default TikaConfig.
> Also since TikaConfig is not serializable, there is no way to assign
> mediaTypeRegistry/bufferedMediaTypeRegistry before calling parse()
