Update library list! (Need MCCI forks of relevant libraries)

The libarary list at https://github.com/mcci-catena/Catena-Arduino-Platform#other-libraries-and-versions-required doesn't mention https://github.com/mcci-catena/Adafruit_FRAM_I2C.  We need to make sure *all* the libraries are mentioned.

Indeed we should simply replace the FRAM library, as it's small and will fit in C-A-P w/o problems. But that's a separate issue.
