converter: Improve bit_position computation
- Fix wrong bit_position swap computed:
Need to multiply then lenght in bytes by 8 to get it for bits.
- Add a continental bit_position function:
This allow to get the correct bit_position using the weird Continental.
bit numbering method where the Frame is read using little endianness
and bit count using a big endianness
- Use define CHAR_BIT instead of hardcoded 8 value
