Rewrite the CLI in yargs

[GeorgeCadwallader]

Problem to solve

We have decided to move away from using oclif as the framework that Conventional Tools is built upon.

It has recently become quite temperamental, such as dependabot failed pipelines for oclif version bumps etc.

Proposal

Move over to use yargs instead.

We had already thought about re-writing certain parts of the application anyway, so this is a good opportunity to look at other Node.js CLI libraries.
