Binary sensor map implementation (#551)
* add binary_sensor_map c code * add python file * fixed python and C++ code for new framework * renamed add_sensor to add_channel * travis * Updates - Use struct for channels_ array - heap allocation is not really necessary here. - any_active can also be written as mask != 0 - Update setup priority to DATA - Use shorter TAG (name is already long; not important) - Quotes around name - Add icon to sensor - Use new cv.typed_schema - Change CONF_CHANNEL to CONF_BINARY_SENSOR - makes it clearer that this option accepts a binary sensor (and not for example an int) - Add test Co-authored-by: Otto Winter <otto@otto-winter.com>
