In order to support the ks240 which has children for the fan and light
components, this PR adds those modules at the parent level and hides the
children so it looks like a single device to consumers. It also decides
which modules not to take from the child because the child does not
support them even though it say it does. It does this for now via a
fixed list, e.g. `Time`, `Firmware` etc.
Also adds fixtures from two versions and corresponding tests.
Add SMART.KASAHUB to the map of supported devices.
This also adds fixture files for KH100, KE100, and T310, and adapts affected modules and their tests accordingly.
