* Common interface for Pico plugins

* For a list of supported events see {@see DummyPlugin}; you can use
* {@see DummyPlugin} as template for new plugins. For a list of deprecated
* events see {@see PicoDeprecated}.
*
* If you're developing a new plugin, you MUST both implement this interface
* and define the class constant `API_VERSION`. You SHOULD always use the
* API version of Pico's latest milestone when releasing a plugin. If you're
* developing a new version of an existing plugin, it is strongly recommended
* to update your plugin to use Pico's latest API version.
