🐞 Description of the bug

In the ece_export_for_twinbuilder.py example, the '' character is used in quite a few places as a line continuation character while generating the SML output.

When building the documentation in newer versions of Python, this flags up that we are using unescaped '' characters in quite a few places:

There seem to be 7 locations where this is done:
:690: SyntaxWarning: invalid escape sequence '\ '
:693: SyntaxWarning: invalid escape sequence '\ '
:704: SyntaxWarning: invalid escape sequence '\ '
:713: SyntaxWarning: invalid escape sequence '\ '
:722: SyntaxWarning: invalid escape sequence '\ '
:730: SyntaxWarning: invalid escape sequence '\ '
:734: SyntaxWarning: invalid escape sequence '\ '

If we had "\" as a string, this would give us a syntax error, but as we effectively have "\ " this just raises a SyntaxWarning, and the SML file seems to be generated as expected.

I think the fix is as simple as replacing the 7 instances of '\ ' with '\\ ' (see https://docs.python.org/3/reference/lexical_analysis.html#escape-sequences).
