Add read-only Js5Index.{Group,File} types
...
These will be used by the high-level cache API, where we don't want to
expose mutable versions of the group/file types as that would allow the
index/cache to get out of sync.

Replace readAllBytes() with readBytes()

It's more concise and I suspect Kotlin's implementation is better than
Java's, as it seems to take available() into account.

Ignore trailing blocks with a non-zero next block pointer
...
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.

Add support for the current master index format
...
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.

Combine key validation with uncompression
...
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.
