[Feature] Make coordinates in zone definition templateable

[Aaroneisele55]

Hello, I have been using this component for about 2 months now and it has been rock solid!

However, as seems to be the case with mmWave, there is a lot of fine-tuning and calibration needed, which includes changing the coordinates of zone polygon points.

Could you please make those templatable so I could set them from e.g a text input field in HA?

This is not urgent in any way, I can still recompile every time I change the coordinates, but it would make fine-tuning and initial setup much easier especially for bugfixing (e.g sensor zone too big) so you can adjust it dynamically while testing.

Best regards Aaron Eisele
