Safer IEEE754 conversion. 
The conversion given assumed two things:

1. the pointer was either 32-bit aligned or that unaligned word access
   was safe.  (Not the case on ARM)

We avoid this by using memcpy to copy to a buffer that *is*
32-bit-word-aligned.

2. the word was in native-endian format.

The original code appeared to assume the given word would be in
big-endian format (aka "network" byte order), so we convert it to the
host's native format before casting.

We re-instate the original implementation, controlled by a compiler
switch to allow easy rollback if problems are encountered.

0fccc0e337 Add a function to calculate the manufacturer ID from the 3 byte ASCII 
code. The formula can be found at http://www.m-bus.com/files/w4b21021.pdf,
chapter 3.3 at page 6.

This obsoletes the static defines, so remove them.
