`ncu-ci` wait for CI to finish and send desktop notification

[mmarchini]

As title says, ncu-ci could (optionally) wait for a pending CI and send a desktop notification when it's finished, as well as outputting the result.

Something like:

$ ncu-ci --wait url https://ci.nodejs.org/job/node-test-pull-request/29730/

⠏  Waiting for CI to complete
