[FEAT] Decrypt other traceroutes and direct messages.

[JonasGhost]

Is your feature request related to a problem? Please describe.
My issues are problems with the radios. To debug them, I need to receive the traceroute results even when the result does not reach the sender.
So I tried building a network sniffer, less successful. I adapted an existing tool meshtastic UDP to decide and decrypt these packages.

Describe the solution you'd like
. I'd like an option to store multiple private keys of "testing" node inside the meshmonitor.
If a package or traceroute for one of these devices arrive, I'd like it to be recorded and decrypted.
Optionally also a notification over telegram.
Another thing would be an UI where all the records can be read.

Describe alternatives you've considered
Alternative, creating a Lora to UDP repeater Node (mode repeater, Lora transmission deactivated, untested)
And work with the existing UDP tool

Additional context

Look at "Channel Database", it already does this.

However, the Meshtastic Firmware does not relay traceroutes back to a client unless the begin or end with the locally connected device, there is no way to "sniff" traceroutes in flight. It will relay message packets, however.
