support Deflate64 compression method (was "zip64 support")

[Former user]

Looks like fuse-zip is unable to work with zip64 archives:

I'm using fuse-zip 0.6.0 and libzip 1.5.2

From syslog:

Jun 13 22:40:33 monolith fuse-zip[25524]: Compression method not supported

Seems that this issue is related to a compression method not supported by libzip.

I will look deeper into this file at the weekend.

test.txt is compressed using Deflate64 algorithm that is not currently supported by libzip. I’ve created a feature request in libzip’s issue tracker: https://github.com/nih-at/libzip/issues/116 .
