fixed set_multi_macfilter_settings documentation + added an example

[TheLime1]

i fixed the documentation based on the payload i found in the dev tools

<?xml version="1.0" encoding="UTF-8"?>
<request>
    <Ssids>
        <Ssid>
            <WifiMacFilterMac0>66:77:88:99:AA:BB</WifiMacFilterMac0>
            <wifihostname0>66:77:88:99:AA:BB</wifihostname0>
            <Index>0</Index>
            <WifiMacFilterStatus>2</WifiMacFilterStatus>
        </Ssid>
    </Ssids>
</request>

What i know for now is <WifiMacFilterStatus>2</WifiMacFilterStatus> add to the block list , no idea how to add to the whitelist
also if you SET another mac adr in the same index it will replace it
