Replaced SHA-224 with BLAKE2s

Also changed the hash determiner format such that each IV, as well as
the Shedinja flag, has its own byte. This increases the size of the
determiner to 16 bytes, 33 bits of which are always unset. While this is
somewhat wasteful, it is useful for debugging purposes because it is
hard to predict the behavior of bitfields.

For testing purposes, the amount of time that the Wii waits for the GBA
to compute hashes has been increased. Given that BLAKE2s is a generally
faster algorithm than SHA-224, it will likely be safe to decrease this
delay in a future commit.

Because the hash algorithm has changed, all old hashes are now invalid.
