plutil writes years past 9999 and negative years in a form the pinned
XML decoder cannot parse, and binary plists can hold dates outside the
JavaScript Date range. The decoder returns an Invalid Date. Its
projection's toISOString() call then threw, so inspect_plist failed the
whole plist as "unreadable_output" with a `rea doctor` remediation.
Keyed archive inspection and Interface Builder decoding rejected the
archive in the same way.
projectPlistValue, the shared projection, now reports such a date as
{ "$plist_type": "date", "iso8601": null } and counts it. inspect_plist,
keyed archive inspection and Interface Builder decoding each add a
counted limitation, as they already do for non-finite reals.
