RFC: Add rad2deg, deg2rad for Taylor1 and TaylorN

[PerezHz]

Self-explaining title 😉... Was working with these functions with Taylor1 and thought it'd be nice to add them to TaylorSeries!

Thanks! LGTM!

If you are using it together with TaylorIntegration, it is maybe a good idea to include the equivalent mutating functions, e.g., rad2deg(res, a, k). This is of interest in the context of PerezHz/TaylorIntegration.jl#31

That's actually a really nice suggestion! Sure, I'll add them right away!

Be sure to add them in the dictionaries that are used in TaylorIntegration. Let me know when you are ready...

I just noticed that you will have to rebase...

Good catch! Just rebased to current master, added the mutating functions, updated the Dicts and also added corresponding tests

[PerezHz]

Just saw that #143 is about to be merged... I can re-rebase to latest master once that PR is merged

Thanks a lot!
