Refactor the current SAMP message for memory efficiency
and scalability. Introduce per-span and per-detector
information structures, in place of separate static
arrays for each 80MHz segment in SAMP message structure.
Also, remove members in the SAMP message that are no
longer in use.
The new structures will be under OPTIMIZED_SAMP_MESSAGE
flag, which is unset by default for all profiles, till
development is complete.
