Fix non-snake case conversion to pascal case

[tordnat]

Closes #455

Cool, thanks for this - my initial question was going to be whether we can avoid generating these hybrid case python function names like PinholePose_pred_decrease_times_two, but I see Caspar is doing that internally I guess by concatenating the class name and a snake_case function name. Feels like you could instead have Caspar convert the class names to snake_case for use in the kernel name, but that could be confusing in more complicated cases.

I think this seems reasonable, partly curious what @emillma thinks for whether it'd be more reasonable for Caspar to handle this somewhere else instead

[emillma]

I'm pretty sure Caspar could handle stuff better, but I'm afraid you will end up breaking some conventions no matter what you do. We are generating names for C++ and Python where certain names are partially used for both class names, function names and variables 🍝 If this fix solves it I think it might be a good enough solution for now.

[emillma]

In the future it might be a good idea to add a strict keyword argument, to make the conversation only support names that follow the expected convention.

Makes sense, thanks
