Use non default Chip name and layer number

Information

• Qiskit Metal version:
• Python version:
• Operating system:

What is the current behavior?

@Ray Parker was using non default chip name and could not create a gds file as desired.

add_qgeometry needs to have to updated chip name and layer number. If the chip and layer number have not been added, then use the latest values from options, not the default.

Steps to reproduce the problem

Conversation in Slack #metal.

What is the expected behavior?

As an afterthought, I think there should also be a check for the chip name existing with design.chips. If the chip information is not there for that chip name, need to give an error.
