Constant `ZIP64_ENTRY_THR`

const ZIP64_ENTRY_THR: usize = 65_535usize

The number of entries within a single zip necessary to allocate a zip64 central directory record.

If more than this number of entries is written to a crate::ZipWriter, then [crate::ZipWriter::finish()] will write out extra zip64 data to the end of the zip file.
