[WIP] quickrun result error inspection

[dwhswenson]

This adds an inspect-result command to the CLI, which takes a result JSON file and outputs some basic information on each unit.

The information included here can definitely be expanded later (timings, possibly more details on simulation parameters, etc). But I thought it was most urgent to get error messages out.

Here's an example output from an edge that had a NaN failure:

$ openfe inspect-result easy_rbfe_lig_ejm_46_solvent_lig_jmc_28_solvent.json
This edge was a SUCCESS.
This edge consists of 4 units.

Unit ProtocolUnitResult-e8e4c380537f4bfd89639cf52b8a8b95 ran successfully.

Unit ProtocolUnitFailure-4c981804da4c40b198d7fc310401c755 failed with an error:
SimulationNaNError: Propagating replica 1 at state 1 resulted in a NaN!

Still needs tests, so that'll come after review comments on output.

ah, shoot, this PR has mixed in some other stuff. I'll move the file to a clean PR.
