Fix typo, celsius vs celcius
Add a category on THMThermodo to easily convert the temperature readings to other units. Keep the category as an instance method, in case THMThermodo ever adds an option to pre-define the temperature unit, in which case the maths in the category would need adjusting.
Remove a new line in the README.md file that should be a space instead.
