Remove Chadoq2 device

[madagra]

The Chadoq2 device is currently deprecated and it should be removed.

[HGSilveri]

Rather than removing Chadoq2 altogether - which would be quite disruptive to existing code - I propose the following steps:

• [ ] Create a DigitalAnalogDevice with identical specs to Chadoq2
• [ ] Replace usage of Chadoq2with DigitalAnalogDevice throughout the codebase (including tests and tutorials)
• [ ] Raise a DeprecationWarning in Sequence's created with Chadoq2, recommending the usage of DigtalAnalogDevice instead (we can do the same with IroiseMVP)

@madagra @a-corni Do you agree with these steps? Would a different name perhaps be better? I also thought of HybridDevice which is shorter but vaguer

I agree with these steps ! I prefer DigitalAnalogDevice to HybridDevice, I think it's more explicit.

Let's go ahead with DigitalAnalogDevice.
