v0.0.33

I am developing a self-hosted custom iClock web software. For iClock, the pushcommkey is optionally used for authentication purposes. Therefore, I have introduced the following methods:

setPushCommKey()
Set PushCommandKey
Example:

$zktecoLib->setPushCommKey('TokenComnKey'); 

getPushCommKey()
Retrieve PushCommKey.
Example:

$zktecoLib->getPushCommKey('); // Returns: "TokenComnKey"
