It seems that the process keeps a lot of open connections to Chromecast devices during playback.

The most likely culprit is the _refresh_chromecasts logic.

We should start a cast object and register a status listener only if a Chromecast with the same identifier isn't already registered in the plugin.

Closes: #389

`mdns` connection are another culprit for the increasing number of open
files in the process.

- `pychromecast.get_chromecasts` returns both a list of devices and a
  browser object. Since the Chromecast plugin is the most likely culprit
  of the excessive number of open MDNS sockets, it seems that we may
  need to explicitly stop discovery on the browser and close the
  ZeroConf object after the discovery is done.

- I was still using an ancient version of pychromecast on my RPi4, and I
  didn't notice that more recent versions implemented several breaking
  changes. Adapted the code to cope with those changes.

Explicitly use a `CastBrowser` object initialized at plugin boot instead
of relying on blocking calls to `pychromecast.get_chromecasts`.

1. It enables better event handling via callbacks instead of
   synchronously waiting for scan batches.

2. It optimizes resources - only one Zeroconf and one CastBrowser object
   will be created in the plugin, and destroyed upon stop.

3. No need for separate `get_chromecast`/`_refresh_chromecasts` methods:
   all the scanning is run continuously, so we can just return the
   results from the maps.
