	Mpr121 added debounce and thresholds config (#558)
* fixed code issues from previous PR * travis line to long * travis * more travis * Update esphome/components/mpr121/mpr121.h Co-Authored-By: Otto Winter <otto@otto-winter.com> * fixed issues * fixed issues * fixes remove duplicate line remove threshold settings * fixed touch release thresholds mixup
