Option to slugify column names

[emreakg]

Currently, names of the columns for a single google-sheet data stream is inferred from the first row of the sheet. Due to bad practice from sheet owners, column names often end up with non-ASCII characters, or problematic characters such as newlines. Such cases can be problematic depending on the singer target.

Would it be hard to implement an option to use python-slugify, or another way to standardize strings, to standardize column names?
