Suggestion: Remove LispCons from the name of LispConsEndChecks

...and LispConsCircularChecks

The official rust style guidelines state that redundant prefixes should be avoided. I consider the LispCons part of these type names redundant. As the style guide says, module names should be used to disambiguate - I consider the lists module name perfectly fit for this purpose - or renaming imports in cases where that's necessary.

The current type names are long and take up frustratingly large amounts of line real-estate, for no benefit.

I would have liked to have done this more like C++ or other type systems and defined EndChecks and CircularChecks inside of LispCons and had LispCons::EndChecks.

The lists module is itself not sufficient in my opinion as a name space for these. We could move some of it to a cons.rs which would better map.
