Bricklogger 0.2.0

The first public release of Bricklogger.

Install with

curl -fsSL https://github.com/CX1-ApS/bricklogger/releases/latest/download/install.sh | sudo sh

or run the image ghcr.io/cx1-aps/bricklogger:0.2.0. The documentation is at
https://cx1-aps.github.io/bricklogger/.

Upgrading from 0.1 with an iBOS source

The iBOS source is no longer built in: it is a plugin of its own,
bricklogger-ibos. While sources.yaml names type: ibos and the plugin is not
installed, the daemon does not start: it reports the unknown source type
'ibos'. Add the plugin right after the upgrade and start the daemon again:

bricklogger plugins add bricklogger-ibos
sudo systemctl restart bricklogger

The configuration, the type name, the vocabulary and the collected history are
unchanged, and collection resumes from the latest observation of every point;
the stretch the daemon was down is fetched from the cloud.

Changes

• Bricklogger is published on PyPI, and the install script is a release
  asset; the image is built for released versions only, without an edge
  tag.
• The plugin SDK grows: bricklogger.sdk.bacnet (BACnet's object types and
  the map from its engineering units to QUDT), expand and UnknownPrefix
  for prefixed names, and DURATION_HELP, parse_duration and
  format_duration. A plugin built for 0.1 pins bricklogger<0.2 and is
  released again for 0.2.
• The model explorer keeps systems, collections and zones out of the tree:
  they stand in a band of their own under class headings, and a grouping opens
  to what it gathers. bricklogger model tree --root <grouping> does the same.

Fixes

• A destination whose write fails — after the database restarted, say — is
  stopped and started again before the write is retried, so it reconnects
  instead of retrying on a dead connection forever.
• plugins add and plugins remove no longer miss a plugin installed within
  the same instant as their previous look at the environment.
