Validate Zip Entry Sizes Before Parsing 3MF XML

The 3MF importers read XML entries into a single expat buffer whose size is
an int, while the archive extraction used the entry's 64-bit declared size.
The two could disagree for entries declaring more than INT_MAX bytes.

Reject such entries before allocating, and use one size for the buffer, the
extraction and the parse. This applies to the BBS importer, the PrusaSlicer
importer and the PrusaSlicer fingerprint probe. The load now fails with an
error instead.
