An interactive "lightning-cli" that allows you to interact with a CLN REST endpoint. You MUST use the -k (parameter) and provide key=value pairs for ALL commands requiring parameters. example:
./lighting-cli invoice -k amount_msat=100000 description="test" label="test1"
The first time you run the lightning-cli command, a .env MAY be stubbed out. This is where you put your CLN Rune and REST point information.
