/**
 * Scrypt KDF from RFC 7914.
 * @param password - pass
 * @param salt - salt
 * @param opts - parameters
 * - `N` is cpu/mem work factor (power of 2 e.g. 2**18)
 * - `r` is block size (8 is common), fine-tunes sequential memory read size and performance
 * - `p` is parallelization factor (1 is common)
 * - `dkLen` is output key length in bytes e.g. 32.
 * - `asyncTick` - (default: 10) max time in ms for which async function can block execution
 * - `maxmem` - (default: `1024 ** 3 + 1024` aka 1GB+1KB). A limit that the app could use for scrypt
 * - `onProgress` - callback function that would be executed for progress report
 * @returns Derived key
 * @example
 * scrypt('password', 'salt', { N: 2**18, r: 8, p: 1, dkLen: 32 });
