feat(dfx-orbit): dfx-orbit version 0.4

[Sawchord]

This PR adds a new version of dfx-orbit.

Features

Orbit Request Redesign

• All requests are prefixed with dfx-orbit request
• Requests are paired with dfx-orbit verify commands that can be used to verify requests, by recreating the arguments and checking whether it matches
• --and-aprove --or-reject flags allow to approve / reject requests right away, if verify passes / fails

Display information improvements

• All information outputs (dfx-orbit station show, dfx-orbit me, ...) now have textual (non-json) outputs.
• This information leaves out redundant and unimportant information
• Additional information is pulled from dfx.json and canister_ids.json (if available) to augment the report (e.g. reverse lookup principal names etc.)
• Old output still available using --json flag
