How do I emulate multiple UEFI binaries and their interactions?

[mkrasnitski-tst]

Say I have a pair of UEFI binaries, a driver containing some protocol registration code, and an application which calls LocateProtocol and actually exercises the functionality located in the driver. Since the Qiling() class constructor takes a single argv array for a specific binary, how would I load the driver into memory first before executing the application?
