A quick logger method
Improving message handling - does verification now

This improves the TED message handling, including:
  * TED1000 bit flipping
  * TED1000 lead-in value check
  * checksum verification
Pull TED1000 code into a new file and more docs
Fix Ted1000 message scoping and require it
Calculate power and voltage

This switches the bit-struct definition to use char fields for the raw power so
we can access the bytes later and perform the necessary calculations. We also
add the methods to do the calculations.
