Add new Hankel1 and BesselJ functions that work with CSE (#64)

* Add new Hankel1 and BesselJ functions that work with CSE

Since Derivatives and Subs are not CSEed due to some issues
derivatives of hankel1 functions and hankel1 functions
end up with different arguments and code generation treats
them seperately. See https://github.com/inducer/sumpy/blob/main/sumpy/cse.py#L84



* readability improvement
