New parser request: tsv

[don-rumata]

Hi, can you add support for tsv?

[kellyjonbrazil]

Yep, this should be an easy one. I can alias to the csv parser and just change the delimiter to \t.

tsv support would be great. is there an option or a flog to manually set a delimiter?
i could not find some.

by the way, i really like your tool
