What is the current behavior?

only statically defined dependencies are supported

What is the expected behavior?

Developers need to be able to define a function that has rules about when other fields are required.

For example, if making a HTTP client like curl, you would define flags for 'method' and 'data' (body). The data field is required ONLY WHEN method=POST.

I propose the "dependsOn" flag property be an object rather than an array, where the keys are the names of other fields required, and the values are true or a async function that is passed the complete command context and must return a bool.

Please mention your oclif and OS version.
