TimeDelta sum #1029
Description
Hi!
Thank you for csvkit.
I am wondering if it would be possible to add the "sum feature" for TimeDelta type?
How would I use it?
$ csvstat -c Duration --unique test.csv
2
$ csvstat -c Duration --sum test.csv
None # Here I would expect 4:06:00 instead of None -- sum of the time delta times
$ cat test.csv
Duration
01:16:00
02:50:00
I am happy to submit PR.
Thanks
