Handle ctrl-c in uniq and uniq-by (#7478)
A partial fix for #7477. `uniq` can be slow sometimes, so we should
check `ctrl-c` when it's running.

Tested on [this
file](https://home.treasury.gov/system/files/276/yield-curve-rates-1990-2021.csv),
I ran `open yield-curve-rates-1990-2021.csv | uniq` and confirmed that I
can now cancel the operation.

Future work is needed to figure out why `uniq` is so slow.
