Support for complex gates?

[gsilviHQS]

Hi,
this code is really a great idea, but I was just wondering why there are not R_y gate for example? Is it to avoid having to deal with complex phases?
If there is no intrinsic limit to add those gates I might give it a try and them as well.

There is no Ry gate yet because I didn't need it. Please do give a try implementing it though.

I would make the gate format ry<qubit>,<half_turns> e.g. ry2,0.25 is a pi/4 rotation on q2.

You'll need to implement perform_ry, similar to perform_h:

feynman_path/feynman_path/diagram.py

Line 198 in bb144e6

def perform_h(self, q_i, *, pre_latex=f'', name='H'):

def perform_ry(self, q_i, half_turns, *, pre_latex=f'', name='Ry'):

Also, this line will need to be changed to detect decimal numbers, not just integers:

feynman_path/feynman_path/command.py

Line 10 in bb144e6

args = tuple(int(arg) for arg in gate_str[len(name):].split(','))

Alright, I ll give it a try.
I notice that actually also the simple perform_y is missing. I ll start from that one. If you have suggestions let me know.
