Add --in-place to qsv edit

[rzmk]

Is your feature request related to a problem? Please describe.
The qsv edit command outputs the entire edited data by default but a user may want to edit a file in-place (therefore also not needing to output the entire file).

Describe the solution you'd like
A way to edit a cell for a file in-place, such as adding a --in-place flag.

Not sure how this should be implemented. Currently a manual workaround would be using -o to another file, delete the original, then rename the edited file to the original file's name.

I usually rename the old file to .bak then do the deed writing to the new file, just in case I mess up. Message ID: ***@***.***>
