feature: Export annotations as a CSV (annotations pt. 5)

[ShrimpCryptid]

Problem

Part 5 of 5(?) for #484, annotation prototype.

This change adds the ability to export a CSV containing the annotation data! Each object ID is a row and the labels are listed as columns.

Estimated review size: small, 15 minutes (faster if whitespace changes are disabled)

Solution

• Adds a CSV export button in the annotation.
• Adds a new toCsv() method in AnnotationData, which serializes the annotations to a CSV string.
• Added unit tests for handling bad label names and inputs.

Type of change

• New feature (non-breaking change which adds functionality)

Steps to Verify:

1. Open preview link: https://allen-cell-animated.github.io/timelapse-colorizer/pr-preview-internal/pr-504/
2. Enable annotation mode and annotate several cells with different labels.
3. Click the "Export as CSV" button to save a CSV file.
4. Open the CSV file. It should render with the correct header names in Excel.
