[BUGFIX] .txt file with commas in URLs

[bkj]

The current implementation seems to fail when the URLs in a .txt input file have commas in them. This modification seems to fix the bug.

(Disclaimer: I am not 100% I am passing data the way that's intended ... if so, my mistake and please correct me!)

I am also still having this issue. I get a CSV parse error like the below if the URL has one or more commas:
pyarrow.lib.ArrowInvalid: CSV parse error: Expected 1 columns, got 2: http://1.bp.blogspot.com/-xf8FZNbm-O4/UVbWL6XBdOI/AAAAAAAAFYs/1IPtSSmYZiI/s640/Big+sage,+Lantana ...

let's instead make the separator be something that never occurs

Got the same issue. I change the delimiter from ',' to '\t' and it works (line 100 of reader.py):

df = csv_pa.read_csv(file, read_options=csv_pa.ReadOptions(column_names=["url"]), parse_options=csv_pa.ParseOptions(delimiter="\t"))
