added driver for MLX90614 Temperature sensor

[rahulOCR]

Hey everyone,
I am resubmitting this PR as per code of conduct of Ardupilot after closing #26644
I am submitting this PR to merge into master. I have added MLX90614 temperature sensor into AP_TemperatureSensor library.
Using data-sheet provided [Link of data-sheet]](https://www.melexis.com/en/documents/documentation/datasheets/datasheet-mlx90614). I have used this to get ambient temperature of cabin of battery.

WIKI:

Hi I am attaching datasheet, wiki and photos for interfacing. MLX90614 sensor is an infrared thermometer for non-contact temperature measurements. Both the IR sensitive thermopile detector chip and the signal conditioning ASIC are integrated in the same TO-39 can. Integrated into the MLX90614 are a low noise amplifier, 17-bit ADC and powerful DSP unit thus achieving high accuracy and resolution of the thermometer.

set (examples shown for first sensor):

TEMP1_TYPE = 0:Disabled, 1:TSYS01, 2:MCP9600, 3:MAX31865, 4:TSYS03, 5:Analog, 6:DroneCAN, 7:MLX90614 Sensor type

TEMP1_BUS = 0-3 Board’s I2C port on which the sensor is attached

TEMP1_ADDR = the sensor’s I2C address (0-127). For this sensor, 90

TEMP1_SRC = which other temperature reporting device type should have its temperature report replaced with this sensor’s.

TEMP1_SRC_ID = this identifies which individual device, of the above type, should have its report replaced.

Should be a single commit prefixed with AP_TemperatureSensor:

[peterbarker]

@rahulOCR still working on this one? There's a couple of reviews outstanding

[rahulOCR]

hey @peterbarker I am waiting for some dev call or similar to review and should I squash all commits into one single commit ?

[peterbarker]

This is looking good. Couple of basically whitespace change requests.

I'll mark it for discussion at DevCallEU tonight

[Hwurzburg]

needs build_options.py and extract_features.py files....should be squashed

[peterbarker]

This needs a rebase on master.

SHould be two commits, one Tools:, the other AP_TemperatureSensor:.

You will need to change new to NEW_NOTHROW when allocating the backend - do what we do for the other backends.

[rahulOCR]

@peterbarker I think this NEW_NOTHROW was recently added. will do that

[Hwurzburg]

still needs extract_features.py

[rahulOCR]

Hey @Hwurzburg can you help me out what needs to be changed in extract_featues.py

[Hwurzburg]

@peterbarker would be better at that

[peterbarker]

I've tested this rebased against master (#28143) and it seems to work as expected.

Maybe reading a bit low?

Very long time constants?

Merging, thanks!
