Revert "util/spd_tools: output binaries instead of hexdumps"

Browse Source 
This reverts commit f23794cf04.

Reason for revert: This change breaks compatibility if the changes
in CB:44775 are not also included. CB:44775 is still under discussion,
so revert this change to make spd_tools usable again.
