Move remotes to standalone repo

Since Hue motion sensors are already supported in HA we decided to split motion sensors and remotes into separate repos. This will make it easier to maintain the code, and simplify life for people who just want to use the remotes - not currently officially supported by HA.

Remove a silly warning with the 'buttonevent' of Z3 switches

As title. Also more test coverage

More refactor work

More under the hood fixes

Remove duplicated code in binary_sensor and remote platforms

Under the hood changes to remove duplicated code in binary_sensor and remote platforms, and merge the data source for them.

Usage recommendations

If sub-second delay is not critical for you, but the 5 seconds of the official integration for sensors is too much, and you have remotes (not implemented in HA Core yet), the best configuration would be something like this:

remote:
  - platform: huesensor
    scan_interval: 2

With that, and configuring the binary sensors in HA Core, both remotes and sensors will have a 2-sec update rate.

Many thanks to @azogue for this contribution

Use the same data source as Home Assistant

Under the hood change to help mitigate polling issues

Drop scan rate

Drop from 0.1 to 0.5 seconds polling. If this is still causing issues we can drop further. Anyone who wants to maintain the high interval can see how to change the code here

Hotfix 215

Remove some unneccessary logging that is causing problems

Minor hotfix

Hotfix for #213

Various under the hood improvements

Added some test and did a small refactor

Prevent excessive events

Resolves an issue where remotes were firing events too frequently
