This PR changed scope, and now unifies all proxy iterators under a single template type.

Old PR description

At this point in time, the iterator for MeasurementContainer does not match the std::forward_iterator concept which SonarCloud really wants me to use. In this commit, I make sure that the iterator satisfies the concept.

Unfortunately, this requires a default-initializer, because std::forward_iterator requires std::incrementable which requires std::regular, which requires std::semiregular which in turn requires std::default_initializable which I think is silly.

Do you think it would be easier / beneficial to define it as a random access iterator?

Hmm, probably; I can do that!

This PR has changed scope; rather than have it implement random access only for the measurement iterator, it now captures the proxy iterator for all such containers we have; for measurements but also tracks and spacepoints.

We have quite a few container types whose iterators are container-index
pairs. These currently have different implementations which can be
fairly easily unified under a single template.
