Support for nested subcommands

[Krever]

Is it possible to somehow nest subcommands with mainargs?
I'd like to achieve something like this:

program foo bar --some --arguments
program foo baz --other --args

There isn't a way right now. Could probably be implemented, but not sure what the API would look like (maybe @main on objects that wrap the @main defs?)

We have a similar use case where we have different output writers that require different parameters. Example:

... --outputwriter1 --parameter1 <String> --parameter2  <Int>
... --outputwriter2 --parameter3 <Int> --parameter4 <Int>

So it would be nice to have something like this.

writing to add my support to this one, e.g. the github cli has commands like gh pr create --draft
