First README example does not work

[romainreignier]

Hi!

Thank you for this nice tool.
I quite like the regex support to avoid the multiple spaces issue.

On your first example in the README:

ps aux | hck -d, -f1-3,5-

I have this output:

$ ps aux | hck -d, -f1-3,5-
thread 'main' panicked at 'range end index 3 out of range for slice of length 0', /home/runner/work/hck/hck/src/lib/core.rs:334:25
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

From my understanding, ps aux does not use a comma as delimiter so it does not work.

Thanks for the bug report! I've updated the readme with working examples and fixed the zero splits found issue.

See v0.3.0
