Merge pull request #2306 from stweil/fuzz 
Fix two issues reported by OSS-Fuzz

b3aff7d633 Fix Index-out-of-bounds in IntegerMatcher::UpdateTablesForFeature 
This fixes issue #2299, an issue which was already reported by
static code analyzers and now by OSS-Fuzz, see details at
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=13597.

The Tesseract code assigns an address which is out-of-bounds to a pointer
variable, but increments that variable later. So this is a false positive.

Change the code nevertheless to satisfy OSS-Fuzz.

Stefan Weil
1c7e00611b Add initial support for traineddata files in standard archive formats 
This requires libarchive-dev.

Tesseract can now load traineddata files in any of the archive formats
which are supported by libarchive. Example of a zipped BagIt archive:

    $ unzip -l /usr/local/share/tessdata/zip.traineddata
    Archive:  /usr/local/share/tessdata/zip.traineddata

`combine_tessdata -d` and `combine_tessdata -u` also work.

The traineddata files in the new format can be generated with
standard tools like zip or tar.

More work is needed for other training tools and big endian support.
