Feature Request: Add some status information like Android "Internal Details"

[Sgn-32]

Signal Android shows in the "Internal Details" the status of:

"Sealed Sender mode"
"Phone Number Sharing"
"Phone Number Discoverability"
"Profile Sharing"

Maybe the ServiceId should be shown as default for every contact.
Possibly also the status, whether contact is registered or not

Where would you expect this data, in the listContacts command?

[Sgn-32]

The listContacts command seems to be the best place. Maybe to not overload the default call of listContacts, show the information only with -d, --details

[AsamK]

I've added an --internal parameter that includes this information.
