CLN: Removed duplicated test data
Remove duplicated test data.

"test1.csv" & "tips.csv" are present in both "tests/io/parser/data" & "tests/io/data/csv".

Move the "*.csv.bz2" & "*.csv.gz" files since the s3_resource fixture in tests/io/conftest requires these.

Follow up from: https://github.com/pandas-dev/pandas/issues/29439

Think we should move all the data in io/parser/data/* into io/data/ so it can be re-used. Will save for follow up.
