 * EVALSHA redis command
 * https://redis.io/commands/evalsha
 *
 * Before using it, you need to:
 * 1) call your LUA script using EVAL first, to load it into memory
 * 2) calculate sha1 hash of your script, e.g. using the function in src/commands-utils/sha1.js
 *
 * The rest is exactly like calling EVAL
 *
 * @param sha1
 * @param numberOfKeys
 * @param args
 * @returns {*|Promise<unknown>}
