.dataAlpha as last line consumes last character

[kommisar5150]

If we have a .dataAlpha field as the last line of a .casm file with no new line at the end, the assembler
consumes the last character and replaces it with null. Usually, the new line character would be consumed instead. This is a special case that would need separate handling. Either we enforce coders to add a new line at the end, or we change the .dataAlpha code field a little.

A simple fix could be like this:

            if operands[-1] == "\n":
                instruction += operands[1][:-1].encode("utf-8")
            else:
                instruction += operands[1].encode("utf-8")

Good catch! This bug was in the code since V1.0. Kudos for catching this!
