Add support for simple lambda expressions in forward mode

gojakuch commented 3 weeks ago

This commit provides support for the simplest lambda expressions, that is, those with no captures, in forward mode. The original lambda function is copied into the derivative, but the corresponding lambda class gets extended to also have a pushforward method for the call operator overload. Essentially, there's no visiting of lambda expressions yet (this will be implemented later to support captures, I'm working on this), but rather we allow treating simple cases of lambda functions as functors.
