This is useful in the archiving service code, as it can extract them for
insertion into the database without the overhead of creating and then
throwing away an IntArray.

This already caught some cases of public members that should have been
private and one case where the inferred type was too specific.

This allows us to make them private (rather than internal) and the type
as a whole is immutable.
It does mean we need to convert the key to an IntArray every time we use
it now. However, I hope that the JVM will be smart enough to inline the
toIntArray() method and also smart enough to realise it doesn't escape,
allowing it to allocate it on the stack rather than the heap.
This commit also adds methods for converting XteaKeys to hex, and
converting from hex/integer arrays to an XteaKey object.

Unfortunately we can't use the compiler to guarantee k isn't changed,
though making it internal will help. When the JVM (and Kotlin) get value
types, we might be able to improve on this (e.g. by making it an inline
class of four integers).

This commit updates the tests to ensure all combinations of 0-7 bytes of
leading/trailing blocks of unencrypted bytes work correctly with all
test vectors.

The Resource::compress method already holds entire files in memory at
once, as does the client-side loader. We might as well do the same on
the server-side.

This name is slightly more descriptive and consistent with loader.p12,
which also contains a private key.
I've also removed the public.key file. It isn't read by OpenRS2 and the
two files could get out of sync with each other, which would be
confusing.
It's easy to extract the public key with OpenSSL if necessary:
openssl pkey -in game.key -pubout -out public.key
