including testing headers breaks compilaton on Nano

[dikkedimi]

Including of the test headers gives an error

exit status 1 Error compiling for board Arduino Nano.

You just need Hamming.h for your project. HammingSerial.h is a poorly designed serial adapter that I wrote before I understood the Arduino libraries. The rest is test drivers and the FifoBuffer unit is no longer used. The HammingSerial_Tests code may be useful to show you how to use the class in your project but its not required to include it.

Maybe one of these days I'll package this properly but not today.
