Andreas Eversberg 0c9de251be NMT: Implement Hagelbarger Code
This will correct burst errors of received messages. If the message
is too corrupted, it will be ignored, because some element may not
match then. The digits and line signals are checked for consistency,
since they are repeated serveral times in a message.

Andreas Eversberg 4356c93afa common: Add pre and de emphasis, if the radio does not support it
Connect to the oscillator of the transmitter - good girl!
You need to enable pre emphasis in this case.

Connect to the discriminator of the receiver - good boy!
You need to enable de emphasis in this case.
