Description

Hi. I found that it will be useful for some automatization.
Since we can already write to a file using sqlfluff lint, we can use it with a diff-quality tool. I want to be able to run sqlfluff fix for only changed files.

Right now it is not possible/I didn't find anything useful except just looping through the file parsing it and running sqlfluff fix for each file there.

Use case

I want to be able to point to a file generated by sqlfluff lint when I run sqlfluff fix to fix only a specific set of files.
In the current example, together with diff-quality that gives me linting for only changed files.

Dialect

I don't think this is a dialect thing, but I am using the snowflake dialect.

Are you willing to work on and submit a PR to address the issue?
