Description

On TIKA-1966, one of our users recently shared the newest iOS iWorks files. They've gotten rid of internal .zip and now rely exclusively on .iwa files. commons-compress doesn't currently appear to handle these (snappy-compressed?) files...probably because:

However, the variant of Snappy that is used does not comply with the spec for that format, omitting the stream identifier and checksum.

Any chance you'd be able to modify the snappy decompression to handle Apple's variant?
