This PR adds direct remote access (s3, https) to warc/wet/wat files in S3 buckets, using warcio.

Since 1.8.0, warcio supports direct remote file access over s3 and https: https://github.com/webrecorder/warcio/blob/master/CHANGELIST.rst

This PR adds:

• fsspec_open call from warcio.utils to replace local open call in warcio-iterator.py
• New make target to remote access directly over s3: make iterate-remote-s3
• [Pending moving the files to public bucket] New make target to remote access directly over https: make iterate-remote-https
• New section to README.md to run these targets: Task 2-i: Iterating over "Remote" Files
• New section to use warcio index remotely
• New requirement warcio[s3]>=1.8.0

[ ! Note ]

• I still keep task/target to iterate over local files from the Github repo. (make iterate)
• I think this is a gentle start.
• And might be inviting for people to have the files in their local, to check up close well.
