deadair 0.2.0

• A station can now run plugins it did not ship with. Copy a plugin into plugins/ on the data volume and press Rescan: the station lends it its own SDK, where before every such plugin failed to load. The console marks a plugin you installed, and one that failed to load names the folder it was read from. The plugin SDK is published to npm as @deadair/plugin-sdk, and deadair.radio has a new section on writing, testing and installing a plugin, walking through a complete example.
• Navidrome's plugin page no longer shows the playback authorization card. That card authorizes the station's own track fetcher, which only Spotify uses. Navidrome was being offered a Spotify login it has no use for and, once enabled, a warning that every record would be dropped.
