[Bug] ArrowAnnotateTool doesn't emit annotation modified on the initial draw

[JamesAPetts]

Describe the Bug

This method needs to emit annotation modified:

cornerstone3D/packages/tools/src/tools/annotation/ArrowAnnotateTool.ts

Line 404 in c6d2ca6

_dragCallback = (evt: EventTypes.InteractionEventType): void => {

Also when finishing a new annotation, only completed is fired, so modified is never fired at all other than on the initial click:

cornerstone3D/packages/tools/src/tools/annotation/ArrowAnnotateTool.ts

Line 379 in c6d2ca6

this.configuration.getTextCallback((text) => {

Steps to Reproduce

• Set up a handler to track measurement modified events.
• Draw a new ArrowAnnotateTool annotation.
• Notice an event is only fired at the start, not during moving the arrow, or at finish the arrow.

The current behavior

• Annotation modified events aren't being fired on initial draw whilst modifying the annotation.
• Note that we do emit events when modifying it after initial draw.

The expected behavior

• ArrowAnnotate tool should emit events whilst drawing, so that the final state when you finish drawing can be tracked by consumers.
