fix(users/Profpatsch/netencode): remove Boxes in AST struct r/2147

Apparently HashMap and Vec already do internal boxing, so the extra
indirection in the value isn’t needed.

Then, in order to make things uniform, move the boxing of `Sum` into
the `Tag` value. No extra boxing in the recursion! \o/
