Updated code to allow the use of "pretty" names for the configuration parameters exposed to HomeAssistant, fixing issue #7. The configuration options now use the variable ${device_name_pretty} to set the prefix for the distance, sensitivity, led and mmWave toggle sensor. This variable can be updated in the top section of the sensor.yaml file.
To clean up HA after installing the latest release, remove the espHome device from HA, restart and re-add it.
Also cleaned up the project directory, fixing issue #4.
