Openpathsampling-cli

This release of the OPS CLI includes support for SimStore (starting in OPS 1.4). With the CLI, you can use either SimStore or netcdfplus, but you cannot mix the two.

This version also introduces the `md` command, which will run an arbitrary ensemble until a subtrajectory satisfies it: useful when setting up simulations.

Additionally, several existing commands were made more flexible.

New features and enhancements

* New command: `md` (35)
* Allow multiple uses of --init-conds (34)
* Add --table option in `contents` (33)

The main purpose of the 0.1.1 release is to test the new release process using GitHub Actions.

Miscellaneous improvements

* Switch CI to GitHub Actions (30, 31)
