[Question] How to strip blank,new line from data when importing CSV?

Hi.
I am using vaex.from_csv() to import data but there is no option to strip data.
I saw DataFrameLocal has the
```
df.str.strip()
```
to strip data but vaex.from_csv() returns Generator instead of DataFrameLocal so cant use str.strip().
Note: my csv data is a very large file so cant strip all data in memory

Please help.
