This PR makes reflected binary methods (i.e. `__radd__`) transparent, so that they map directly to the non reflected versions. This differs from the original implementation in #35 (which kept them as separate extensions). That approach had a few flaws: * The `str` representation of binary and non binary operators looked the same, which made them hard to debug. This could have been worked around by non pretty printing the reflective operators (i.e. keeping them as methods instead of operators). * It was hard to define replacements for reflective operators, since they really only were activated on converted/non supported types. This new method is a bit more magic, but should work for any expressions as long as their mathematical operators behave as one would expect for the reversed versions.

This PR adds support for in-place operators in Python, by turning them into pure functions that return the mutated value.
