Require support for Large Message quality for Commands

[pidarped]

The Large Message L quality was introduced for commands that have a large payload(beyond the MRP capacity). Alchemy needs to incorporate this into its xml generation to, potentially, generate something like:

    <command id="0x01" name="WebRTCOffer" direction="commandToServer" response="Y">
      <quality largeMessage="true"/>

We will need changes to ZAP to support this first before making changes here (changes here are easy, but pointless if we don't first make ZAP changes)

see e.g. IS_OPTIONAL
