Add hoplimit argument to override default hopLimit in config

[ppicazo]

Add command line argument for hopLimit to override the default one set in the config for --sendtext, --traceroute, --request-telemetry, and --request-position.

meshtastic --host 192.168.1.10 --traceroute df81f5d7 --hoplimit 5 meshtastic --host 192.168.1.10 --sendtext "hello world" --hoplimit 2

If hoplimit is not specified, defaults to the hoplimit in set in the radio config.

@ianmcorvidae could you take a look at this?

Making some more changes...

Can you add the hopLimit parameter to sendWaypoint and sendAlert since you already address the other two funcs that need it added according to this issue

Hi; sorry it took me quite a while to look into this. Your changes look good to me, so if you're interested in putting it out of draft I think it could be merged.
