Add radiation equivalent dose rate.

Thanks! I ported this to v6 branch also.

Sorry, I'm perhaps a little late for the party, but I'd just like to point out that, IMO, the use of Seconds should be preferred to Hours for the BaseUnit definition, with the latter corresponding to the derived unit of time of SI.

As it stands, the RadiationEquivalentDose would likely throw if asked for it's official SI unit (i.e. using ToUnit(UnitSystem.Si)). We don't have any rules for having a SI base unit present (or be the default) (see #1463) but even if just as a performance consideration- given an operation (like the multiplication with Duration) that operates using the quantities BaseUnits is significantly faster than one requiring a conversion to a non-base unit.

For example, multiplying some RadiationEquivalentDose by "30 minutes" would have the Duration perform a dual conversion from Minutes to Seconds and then from Seconds to Hours, which currently involves extra boxing of the Enum, in addition to asking the ConcurrentDictionary of the UnitConverter for a custom conversion that likely does not exist..

PS I love how the build failed due to the lack of coverage of the operator (and the uncovered lines are finally showing up clearly)- it's very useful in highlighting issues like the one I spotted just now.. 👍

Gotcha, I was thinking about it, but didn't know if seconds made sense in this domain. A quick google reveals that there are conversions for Sievert/second, so sure, we can add that and set it as base unit I guess.

Changed base unit here

Sorry, I'm perhaps a little late for the party :), but. I'm working for the company related to measurement of radiation an I could say that the amount of Sieverts per seconds value could be too small even for Double unit - it's just no sense. I don't know internals of UnitsNet deeply. I added Sv(rem) per hour as base unit widely used in industry.

Not late at all, I'm just pushing too fast here, sorry my bad.

I did find references to Sievert/second, millisievert/second etc. so I assumed it would make sense to include it, mostly to have SI compatible units.

I have no idea if these are reputable sources, but at least more than one source included it.

Ok. Lets see how it will work. Thank you!
