change shebang line to `python2`, or adapt script to Python 3.

[dreirund]

This actually is a Python 2 programme. Up to date is Python 3.

So I suggest that you change the shebang-line (first line of the python script lecroywf.py)
from OLD: #!/usr/bin/python
to NEW: #!/usr/bin/env python2,
or adapt the script it to Python 3.

Regards!

Hey @dreirund,

I have written this code about 11 years ago. If you find this small project useful feel free to open a PR fixing these issues.
Otherwise I will leave the code and your issue here for reference :-)

Cheers,
Chris
