v0.5.0 - Binary Sensor and Dev Container

Thanks again to @amcfague for the two main features of this release:

• Adds Binary Sensors (for use with things like Alarmo, which only handle binary sensors)
• Adds Dev Container support, to make it quicker and easier to set up for development

Additionally, the scapy dependency has been tweaked to use a range rather than assume a version based on the Python version. This should restore compatibility with slightly older versions of Home Assistant which use scapy 2.4.5 on Python 3.10.
