Add comparison operator to python objects under --gen-compare option

[Alex-Ratcliffe]

When --gen-compare is selected this will add a comparison operator to the python classes created when the --gen-object-api is selected. This gives the expected behavior of working object comparisons in the generated code.

I would greatly appreciate if this could receive some attention, so that I can move off my fork for my organizations upstream project. While I realize that it is not recommend to use the object API and as such this isn't a priority, this does add expected behavior for the python generated code.

Hi @Alex-Ratcliffe , I think it needs some tests

Yes Tests would be ideal, but it seems like the generated code is pretty obvious. Can you follow up with the typo and add tests in a follow up PR?
