Created a new photosynq_combined_0_2 which creates 4 separate
lines for the Fs', Fd, Fs, Fd' for the fdirk.  After this,
I'm moving away from saving to the SD card at all and just
pushing everything out through the serial to be picked up
from there.  In addition, this will be the last version which
has all of the options at the beginning - next version you
will simply choose a value between 000 and 999 in order to
indicate which type of protocol you'd like to run.
