If one provides an invalid input to normalizeIotaAddress() it will not return an error, but an invalid string which is not a valid address
Steps To reproduce the bug
import { normalizeIotaAddress } from '@iota/iota-sdk/utils';
// Doesn't care if it's invalid hex chars
console.log(normalizeIotaAddress(" xyz"))
// Empty space isn't checked

0x000000000000000000000000000000000000000000000000000000000000 xyz
0x 0xf60e1cb99687c246c307b637bee7fb5e25b5164c250c628cce83df03b32cbd1a
