New Meshtastic Eliza for communication testing

Setup a new channel with auto responding feature using Eliza chatbot.
This is to facilitate users who want to test receive and response text over meshtastic.

Channel Name = Eliza
Node shortname = RF30
No encryption key


The channel will respond automatically to messages via Eliza. If a message is sent directly to the node, Eliza will also respond.

Hope this provides more interaction, especially to new users.

PS: Someone asked to integrate /eliza as the trigger word at the start of line in the LongFast channel. This has been implemented.
