It would be nice to unify the various statuses a bit more

[mulkieran]

We believe that all statuses have three constructors:

• Error
• Fail
• Working

The first two are nullary, the third contains an argument which is the distinct values that you can obtain from different targets when the target is actually working and stratisd can get this information. This is severely tied in to some other difficult type issues, however.

In the near time, FromStr should be implemented separately for each *DevWorkingStatus part.
