Allow enum to be defined as int parameter

[owenpark8]

Summary

Closes #(Your issue number here)

What features did you add, bugs did you fix, etc?
Allows:

enum class MoteusAuxNumber : int {
    AUX1 = 1,
    AUX2 = 2,
};

MoteusAuxNumber auxNumber;

ParameterWrapper param("limit_switch_aux_number", auxNumber, MoteusAuxNumber::AUX1);

Also style fixes

Did you add documentation to the wiki?

Yes/No (If not explain why not)

How was this code tested?

Tested to work with the enum above. Also made sure it does not compile with enum's without an underlying int type to reduce undefined behavior.

Did you test this in sim?

Yes/No

Did you test this on the rover?

Yes/No

Did you add unit tests?

Yes/No (If not explain why not)

Lmk if this is stupid. I like the enums in the brushless code tho :D

Another fix to make the interface more extensible (if we don't want to keep adding constructors for weird edge cases like this) would be to allow pass by pointer. i.e.:

ParameterWrapper(std::string paramDescriptor, int* variable, int defaultValue = 0) : 
        mType{rclcpp::ParameterType::PARAMETER_INTEGER}, mParamDescriptor{std::move(paramDescriptor)},
        mData{variable}, mDefaultValue{defaultValue}{}

Could allow the user to do funky pointer casting if they wanted to
