Make the serial console printing work with the new packets

[joshdboss]

The new packet format is more versatile, although not yet compatible with the serial console printing.

It should be OK for the sensors with wrappers. Testing is needed, as always.
Some possible improvements:

• Add colors (define the color scheme to use)
• Add units (they are not always documented)

More general issue/question : dataAcquisition always does the setup and cleanup phase, but is called several time (at least once for setup in main.cpp, then in loop). Is this something which should be fixed ? (Split the function in dataAcquisition_setup, ..._core and ..._cleanup ?)
