Add a few more fields to the status group

Add dish direction and "prolonged" obstruction info to the status mode group.

These were added to the grpc service at some point over the last several months.

Only lightly tested, given that my dish no longer reports significant periods of obstruction.

This is related to discussion in issue #27, although it doesn't address that issue in the slightest.
