config: Add LDO Leviathan v1.2 generic config

[meteyou]

This PR contains a generic config for the LDO Leviathan mainboard. I added the temperature sensors at the end because of the 2K2 pullup resistor. If this is not wanted, I can remove them.

Thanks @meteyou for submitting this PR, can you clarify a couple of points? Is there a reason you chose watermark over pid for the bed? and what are these 2 extra temp sensors, are they extra adc ports seperate from the main extruder and heater ports?

Thanks James

@JamesH1978 I just used the octopus pro as base config file. This was with watermark. I can switch to PID (like I use it in my printer).

Yes the leviathan has 4 ADC inputs. They are called TH0, TH1, TH2 and TH3. All 4 ports use a 2k2 pullup resistor. That's the reason why I added it in the config, that the user see the pullup resistor. If you have a better idea, I'm open to change it in the example file.

makes sense, i would name the temperature sensors as such then, TH2 and TH3 so as not to cause confusion. Apart from those small changes, i cant see any reason not to approve

Thanks James

@JamesH1978 i changed the heater_bed to PID and changed the names of the temperature_sensor to TH2 and TH3. i hope this will fit. feel free to ping me, if you have any other solutions/fixes.
