The Beta Parameter is not dimensionless, and has unit kelvin.
Incorporate that into the type system.

if you add kelvin unit to b, don't use self.b.get::<kelvin>(). The unit is correct now.
maybe simplify it into one line?

ThermodynamicTemperatures couldn't be added together, and the same applies to its reciprocal, which is why I did that initially.

Upon further inspection of the uom crate though, turns out I've used the wrong type for Parameters::b, and TemperatureInterval should be used instead, albeit with weird ergonomics, and probably can't be simplified onto just one line.
