No longer receive phone number with first message

Feature Request

Apparently, we no longer receive phone numbers on the first message. See AsamK/signal-cli#1414

In version signal-cli v0.13.0 , there was a flag added --unrestricted-unidentified-sender to the updateAccount command that can be used to receive the phone number in the first message.

As far as I can tell, this is not available yet through the /v1/accounts/{number}/settings, but doesn't seem to challenging to add.
I can see about opening a PR, if you would accept one @bbernhard
