/* Stashes current radio bandwidth and sampling rate.
* Inits to defaults, and restores previous when destroyed.
* The idea here is that an app will eventually call enable
* on the model which will sync all of the model state into
* the radio. We tried lazily setting these using the
* set_configuration_without_update function, but there are
* still various UI components (mainly Waterfall) that need
* the radio set in order to load properly.
* NB: This member must be added before SettingsManager. */
