Update bin/dwhich.dart?

Hey there @bsutton -- getting into all of this.

Could you confirm that dwhich.dart needs to be updated?

It seems to be still using an old Args class from an earlier version of DCLI (3.x.x?)

It also seems that the new ExitException in DCLI 4.x found here:
https://github.com/onepub-dev/dcli/blob/master/dcli_sdk/lib/src/util/exit.dart
or here:
https://github.com/onepub-dev/dcli/blob/master/dcli_sdk/lib/src/util/exceptions.dart

And perhaps a related class here:
https://github.com/onepub-dev/dcli/blob/master/dcli_core/lib/src/util/dcli_exception.dart
and here:
https://github.com/onepub-dev/dcli/blob/master/dcli_core/lib/src/util/run_exception.dart

Let me know if this is relevant/related, happy to get this updated with a bit of direction!

Cheers,
-Tsavo

Comienza con bin/dwhich.dart y compara el uso de Args y de las excepciones con los archivos de DCLI 4.x enlazados en el issue: dcli_sdk/lib/src/util/exit.dart, dcli_sdk/lib/src/util/exceptions.dart, dcli_core/lib/src/util/dcli_exception.dart y dcli_core/lib/src/util/run_exception.dart. Confirma qué APIs están obsoletas y define la finalización como la actualización de dwhich.dart para las interfaces relevantes de DCLI 4.x.
