Description

• Fix bug where erase mode could perist when changing annotation mode
• When user provides an initial_line_size, use that as the default size for new annotations independent of zoom
  • When this argument is not provided, the behavior is unchanged from before (the size of new annotations will still scale with the zoom level).
• Fix bug where the DELETE_CLASS_ID would show up as an option in the id dialog for polygons and bounding boxes

PR Checklist

• Merged latest main
• Version number in package.json has been bumped since last release
• Version numbers match between package package.json and src/version.js
• Ran npm install and npm run build AFTER bumping the version number
• Updated documentation if necessary (currently just in api_spec.md)
• Added changes to changelog.md

Breaking API Changes

For users who have been providing the initial_line_size argument, new annotations that are drawn will no longer scale with the zoom level, and instead will always default to the provided initial_line_size or the most recent size set via the AnnotationResize toolbox item.
