Allow unit values to be defined as aliases and not only the base unit #128

Closed kmcphillips closed 4 years ago

As described in #127 @trcarden, defining the value of a unit using an alias raises.

This happens because we don't have the UnitSystem defined yet that can look up the aliases. It's a chicken egg problem.

So we do the search manually in this case, rather than error. It's not a huge amount of effort, with a little duplication.

I've refactored the with( method to maintain immutability of Unit.

Closes #127

I'll have to fiddle with CI. And there's some unreleated deprecations I'll fix in this release too.
