Add selector of recognized data type

The Feature

Thanks for a great tool!

I set up it running and working not with a meter, but with a radiation dosimeter. My dosimeter has a LCD display so this software works perfectly to get the ambient dose equivalent rate (DER) of gamma and X-ray radiation.

But the only problem I got was that values sent to MQTT and Home Assistant are Value and Rate, calculated on values difference. But in my case, I collecting not a value, but a rate directly. So it will be great to have the ability to select which data is collected - momentary value or rate. Maybe for someone, who uses this tool to recognize the rate of something, this new feature will be useful as well.

Why not do this in Homeassistant?
Just make sure to disable the max rate and neg rate.
