Feature Request add change-nth and change-with-nth actions

[salmankhilji]

• I have read through the manual page (man fzf)
• I have the latest version of fzf
• I have searched through the existing issues

Problem / Steps to reproduce

Using a customized version of rigrep integration as explained within the Advanced examples, after I reload my data, I'd like to be able to change the column that fzf searches in. At the moment, this option is only set using the CLI options and it would be nice to be able to change that at runtime.

I have just realized that for my specific scenario, I can use --nth=-1 as all of my data needs to limit the search scope to the very last column. (I had not discovered negative numbers when I filed this feature request.)

Hence the priority to implement this feature may be dropped.
