Integration of the Daikin Mock API

[ThibautTrarbach]

Hello,

Here is a code update that enables the use of Daikin’s mock APIs.

I added an option to activate the mock APIs, as well as an option to select the device you want to test.

I also added an enum listing the devices currently available through Daikin’s mock API.

From my tests, I haven't observed any impact on the main API.

Thanks in advance, Thibaut
