std.zip: Add ZIP64 support for local file header extra field ...

This PR adds support for handling ZIP64 format in local file headers,
when a zip file contains entries where the compressed or uncompressed
size fields are set to 0xFFFFFFFF, and the extra field contains ZIP64
extended information tag (0x0001)

The code now:

Reads the actual sizes from the ZIP64 extra field data
Validates these sizes against the entry's compressed and uncompressed sizes

Zip file format spec.: https://pkware.cachefly.net/webdocs/casestudies/APPNOTE.TXT

This change allows proper extraction of ZIP files that use ZIP64 format in their
local file headers.
