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
