Long term statistics support

[Jestur]

Thanks for your work on this integration it works well and opens up a host of options for monitoring and managing blood glucose outside of the libre app.
At present the blood glucose measurement results show as per setup in the recorder (14 days in my setup) it would be great if the entity was compatible with the long term statistics. if i understand the docs here - it may be a relatively simple modification of the sensor : https://developers.home-assistant.io/docs/core/entity/sensor/#long-term-statistics
thanks
