Support for external Status widgets 
[###](url) Feature Description

Hi, first of all thanks for this nice project. I'd like to implement an custom status widget at the status screen (where log, date, network widget are placed) using your project.
As far as i can see, the only way is to somehow modify the status module here https://github.com/oznu/homebridge-config-ui-x/blob/master/ui/src/app/modules/status/status.module.ts which lists all widgets in a static way. 

The widget itself should come with my platform plugin to show charging / discharging of my alpha ess home energy battery and is therefore only useful with my plugin. see -> https://github.com/zerwuff/homebridge-alphaess/ 

What would be the best way to adapt the list of widgets from config-ui-x and bring my own widget to the ui to it ? 
Or are there no plans to extend them ? Thanks for your suggestions, Jens
