KC868-M16 configure yaml for ESPhome

[admin]

Yes, there are calibration configurations in the program, which parameters can be modified.
filters:
- calibrate_linear:
# Measured value of 0 maps to 0A
- 0 -> 0
# Known load: 4.0A
# Value shown in logs: 0.1333A
- 0.31749 -> 8.95608

you can test some different load, create as many as possible with different scale parameters:
such as:

filters:
- calibrate_linear:
- 0 -> 0
- x.xxxxx -> 3
- x.xxxxx -> 6
- x.xxxxx -> 9
- x.xxxxx -> 15
- x.xxxxx -> 18

The more parameters, the more accurate they are.
