Wrong Exception thrown (and message shown) for zip files with a large amount of files

[nielsdrost]

If a file with over 1000 entries is previed with Invenio (in this case on Zenodo) the error message seems to be "Zipfile is not previewable" instead of "Zipfile is too large to preview" which I would expect.

The zip previewer seem to throw the wrong exception when a file with >1000 files is previewed. I would expect a zipfile.LargeZipFile to be thrown. But perhaps I am not understanding the code correctly.

invenio-previewer/invenio_previewer/extensions/zip.py

Line 41 in 10233a0

raise BufferError('Too many files inside the ZIP file.')
