ENH: skip_blank_columns in read_csv
- [ ] closes #34231
- [ ] adds skip_blank_columns functionality
- [ ] updates API documentation

Is this any different than calling `.dropna` on the frame after parsing? We have a *ton* of keywords as is in read_csv and tend not to expand that further Thanks for the PR, but it appears that there is not much interest this particular implementation of this feature. I think more discussion should live in the original issue, https://github.com/pandas-dev/pandas/issues/34231, before moving forward with a PR. Closing.
