While the client doesn't appear to be capable of producing a trailing
block with a non-zero next block pointer (though I may have misread the
code), there are caches out there in the wild with trailing non-zero
next block pointers.
When it is reading a group, the client ignores these.
Therefore, for compatibility with the client and existing caches, this
commit removes the StoreCorruptException thrown in this case.

I'm not sure if the auto-detection code works: I'm assuming that the new
format was introduced at the same time as the lengths flag in Js5Index,
but I haven't confirmed this.

As key validation has to uncompress the data anyway to confirm the key
is valid, it seems silly to uncompress twice given everywhere we
performed key validation immediately uncompressed the container
afterwards.

This commit also changes the way the master index format detection
works, as the previous scheme could not distinguish VERSIONED from
WHIRLPOOL.

Originally I used a singleton map if possible, to reduce overhead in the
common case of a group containing a single file. However, the
work-in-progress Cache class needs to mutate the map.
Eventually my plan is to replace the Int2ObjectSortedMaps in Js5Index
and Group with arrays, solving both the overhead and mutation problems.

As we're comparing a real directory tree with Jimfs, we need to ensure
the platform matches - otherwise it gets confused, and thinks \ is part
of a UNIX file name.
Most of these names come directly from the NXT/TFU clients, though a few
are made up as we don't know the official name.

Spotted by Desetude.
I think this was an accident, as the similar Js5Index.Entry class can't
be a data class (as it contains an array).

This will eventually hold the names of each JS5 archive in 550, as and
when I confirm the names from the NXT beta client still match up with
the functionality of each archive in 550.
Currently it only holds then name of index 255.
