Fix dropped frames calculation

[beauwright]

The drop_frame_adjustment function could return a result that was 1-3 frames off. Took a stab at fixing it based on David Heidelberger's pseudocode and it seems to work correctly now.

Thank you for the PR!

It looks like there are a lot of unrelated changes due to your work being based on main instead of dev. main has a lot of extra files added by the release process in CI.

Would you mind making your changes to the dev branch of your fork instead, then make a new PR targeting this repo's dev?

Thanks!

It also looks like you are getting some clippy warnings in CI.

You can run make lint to run all my linters locally

Please also add some tests to assert that the bad cases have been fixed to prevent regressions!

Ideally we would also assert that the internal time representation equals the expected representation for the equivalent non-drop values.

Understood, I'll update the PR with the change on the dev branch, Clippy warning fixed, and tests added in the next day or two 👍
