yescrypt 0.1.1

Ruby C extension wrapping the yescrypt password hashing algorithm. yescrypt is the default password hash in modern Linux distributions (glibc 2.36+). It extends scrypt with pwxform for stronger time-memory tradeoff resistance. Supports YESCRYPT_WORM (scrypt-compatible), YESCRYPT_RW, and YESCRYPT_DEFAULTS flavors.
