Subject: [PATCH] Add hash-bench-gb to Demos

A hash-algorithm benchmark cartridge that times 18 cryptographic and
non-cryptographic hashes on the SM83 (CRC-8/16/32, Adler-32, Fletcher-
16/32, Pearson-8, DJB2, FNV-1a, Knuth, Jenkins-OAT, PJW, SDBM,
Murmur3-32, xxHash32, MD4, MD5, SHA-1) and displays ms/iter + KB/s on
screen.  Part of an open-source cross-platform suite that runs the
same algorithm sources unmodified on seven Nintendo consoles, which
makes it useful for "what does each console actually buy you" CPU
comparisons rather than as a single-target demo.

Sister entries will be submitted to awesome-n64-development /
awesome-gbadev / awesome-dsdev / awesome-8bitgamedev as separate
PRs in their respective repos; they don't touch this list.

Tested in mGBA, BGB, and SameBoy.
