/**
 * Argon2 KDF from RFC 9106. Can be used to create a key from password and salt.
 * We suggest to use Scrypt. JS Argon is 2-10x slower than native code because of 64-bitness:
 * * argon uses uint64, but JS doesn't have fast uint64array
 * * uint64 multiplication is 1/3 of time
 * * `P` function would be very nice with u64, because most of value will be in registers,
 *   hovewer with u32 it will require 32 registers, which is too much.
 * * JS arrays do slow bound checks, so reading from `A2_BUF` slows it down
 * @module
