Resolve Frame Drop Issue in Video Frame Reduction

[raykim2414]

Summary of the Changes

This PR specifically addresses the frame drop issue encountered during the frame reduction process in FYVideoCompressor. The changes made are:

1. Improvement in Frame Reduction Logic: The reduce method in ReduceFrameEvenlySpaced has been modified to correctly handle frame indexes, using originalFPS * videoDuration as the loop condition. This effectively prevents frame drops, ensuring that each frame is appropriately processed.

2. Refinement of Video Compression Settings: The video settings in the createVideoSettingsWithBitrate function have been refined to use targetFPS accurately, ensuring consistent frame rates during video compression.

Testing and Verification

These changes have been rigorously tested with various video files to ensure the frame drop issue is effectively resolved.

Invitation for Review

I would appreciate feedback from the FYVideoCompressor maintainers and contributors on these changes.
