Add MPR121 Capacitive Touch Sensor (#449)
* module mpr121 * added mpr121 sensor and binary sensor * added tests * removed CONF_CHANNELS, it is not supported in the esphome-code mpr121 code * changed namespace for mpr121 to binary_sensor * Update esphome/components/binary_sensor/mpr121.py Co-Authored-By: mvturnho <qris.online@gmail.com> * fixed class names * fix lint errors
