Feature track table improvements

[dlrice]

Purpose

• Show amino acids upon initial display of nightingale tracks
• Scroll table on nightingale navigation change
• Feature table expand button incorrectly being shown
• Animate navigation changes

Approach

• useAnimateRange: animates between initial and final nightingale navigation (start, end) pairs.
• useFeatureViewScrollSync: synchronizes the movement of the nightingale navigation and the table. Note sync only happens from navigation to table and not the other way around.
• Add utility functions to support these

Testing

Added tests

Checklist

• My PR is scoped properly, and “does one thing only”
• I have reviewed my own code
• I have checked that linting checks pass and type safety is respected
• I have checked that tests pass and coverage has at least improved, and if not explained the reasons why
• If needed, the changes have been previewed (eg on wwwdev) by all interested parties.

I feel an explanation in the comments would be more helpful when we refer to it in the future
