Convert an Uint8Array to WordArray

@param {Uint8Array} ua - An Uint8Array
@param {number} uaLength - The Uint8Array length

@return {WordArray}
function(ua, uaLength) {
    let temp = [];
    for (let i = 0; i < uaLength; i += 4) {
        let x = ua[i] * 0x1000000 + (ua[i + 1] || 0) * 0x10000 + (ua[i + 2] || 0) * 0x100 + (ua[i + 3] || 0);
        temp.push((x > 0x7fffffff) ? x - 0x100000000 : x);
    }
    return CryptoJS.lib.WordArray.create(temp, uaLength);
