6 pdm microphones with MEMSMIC1 example

[greenthumb]

Hello, I am currently running the MEMSMIC1 audio streaming example via usb with 4 channels and it works fine, but Because i am using the nucleo-wb55 board that has a pdm interface supporting up to 3 microphone pairs I want to use as many microphones as possible.

Which specific files in the memsmic1 project do i need to adjust to support the streaming of 6 microphones?
