Create a service for NKT fianium

[pbaudoz]

This PR aims to setup a service for Fianium + Varia config.

Todo:

• Adjust simulated service to follow changes in hardware service.
• Update service docs for the NKT.

I feel like combining the Fanium with the current nkt_superk service should be doable. It'd just require changing an enum and setting the right values when creating the methods on the class. Right now, creating the functions is done as

catkit2/catkit2/services/nkt_superk/nkt_superk.py

Lines 235 to 237 in e3f5912

	get_base_temperature = read_register(registerReadS16, Evo.REG_BASE_TEMPERATURE, ratio=0.1)
	get_supply_voltage = read_register(registerReadU16, Evo.REG_SUPPLY_VOLTAGE, ratio=0.001)
	get_external_control_input = read_register(registerReadU16, Evo.REG_EXTERNAL_CONTROL_INPUT, ratio=0.001)

etc...

But you can do the same in the __init__(). Something like:

def __init__(self, ...):
    ... # Other setup code.
    
    connected_device = self.config['connected_device'].lower()
    if connected_device == 'evo':
        device = Evo
    elif connected_device == 'fanium':
        device = Fanium
    else:
        raise NotImplementedError(f'Connected device {connected_device} not implemented.')
    
    # Common functions between Evo and Fanium.
    self.get_emission = read_register(registerReadU8, device.REG_EMISSION, ratio=0.5)
    self.get_emission = read_register(registerReadU8, device.REG_EMISSION, ratio=0.5)
    
    if device is Evo:
        self.get_base_temperature = read_register(registerReadS16, Evo.REG_BASE_TEMPERATURE, ratio=0.1)
    
    if device is Fanium:
        ... # Fanium specific functions.

Does that work for you?

Looks great so far! Left some comments for further steps. We can go through how to work through failed CI tests and how to adapt the simulated service later.

[ivalaginja]

If you have double-checked that the Fianium doesn't have any of these, delete them all. Together with the "added" comments, since that is obvious from the code.

[ivalaginja]

I am pretty sure we'll need an update function for the Fianium as well. For that you will need to check what you can read from it with some sort of "get" functions I suppose, similar to the Evo.
