adding temperature reading

[jposada202020]

PR is to add the ability to read the temperature provided by the sensor. solves #32

Dessign Choices

1. I did not include the temperature as a @Property as the library is already big, and I do no beleive that the purpose of the sensor is to measure temperature.
2. We could read the 4 values at the same time changing _CMD_AXIS_ALL to = const(0xF) , and give them to the user, however I choose not to, because sensor application. Temeprature will need to read register 0x24 adding time to get the value.
3. Put the temperature reading as a optional for folks that would need it

PR could be test using the following script

        SENSOR.display_status()
    time.sleep(1.0)

Please make it a property so it is consistent with other libraries. It shouldn't be much bigger as a property.

Will do :). Thanks

[jposada202020]

Added as a property and included an example to test and further reference

Thank you!
