Recreate ring debt shaking animation in code so that it can be toggled off with reducevfx.

The existing ring debt shaking animation has been recreated via manipulating sprite offsets in the code. This is to allow the shaking to be toggled off for reducevfx. To my understanding, this should avoid any issues with potential desyncs, and that hopefully should hold true.

This PK3 should be loaded to test the changes properly - it modifies the existing animation to only use the small and large static frames, so that the shaking can be re-implemented in code.

A demonstration of the changes in action. (Ignore the error messages, this was recorded in a custom build with additional changes implemented.) ringracers0094
