Allow the user to control how chroma does the fingerprinting

Description

This is a workaround to #5171. It does not adress the underlying problem. But
I think the patch might be worth including anyway.

To Do

• Documentation. (If you've added a new command-line flag, for example, find the appropriate page under docs/ to describe it.)
• Changelog. (Add an entry to docs/changelog.rst to the bottom of one of the lists near the top of the document.)
• Tests. (Very much encouraged but not strictly required.)
