[Feature Request] Add ability to display both Celsius and Fahrenheit

[puterboy]

Love this plugin!
Add ability to display both Celsius and Fahrenheit where the secondary scale is displayed in parentheses (like in the Navbar Temperature plugin).
This is important in the U.S. where we still "think" Fahrenheit but specify tool and bed temps in Celsius.

Should be fixed in https://github.com/LazeMSS/OctoPrint-TopTemp/releases/tag/0.0.2.0 - please reopen if not working/fixed as expected

Thanks! Seems to be working well!
