v0.9.1

While these are still "pre-v1" releases, significant work has been ongoing with schedview and it is approaching v1.0 release.
(thus this release note, to update from the only existing earlier alpha versions).

This release of schedview supports prenight and scheduler_dashboard apps.
The prenight app provides an overview of a night to a few night's worth of scheduling information. Please see the documentation at https://schedview.lsst.io/usage.html#running-prenight and the demo notebook at schedview/notebooks/prenight.ipynb for more information.
The scheduler_dashboard app provides insight into the current state of the FBS scheduler at a point in time, showing feasibility and maps of the basis functions reward values over the sky to show why a particular observation is requested. More documentation will be available for this mode shortly.
