Tool State Restoration via JSON Upload

Summary: Annotations from previous session should be able to be retrieved from downloaded JSON file.

Current Findings: 5/20: Issues with updateFromJSON function:

if paintEventData is undefined, updateFromJSON will fail.
ArrayBuffer not transferring properly into json file, showing up as length 0
When values in labelmap3D and labelmap2D are updated in tool state, labelmaps are not updated on image.

Attempts made to correct:

imitation of OHIF/Viewers/Packages/ohif-viewerbase/client/lib/handleSRs.js loadSRTools() function
Attempt to extract key values from tools and overwrite in the cornerstoneTools.store.state.tools, then explicit call to cornerstone.updateImage(enabledElement). (https://groups.google.com/g/cornerstone-platform/c/39_E-qASafY)
attempt to set tool state manager, add all tools, then restore tool values.
attempt to access and manipulate imageIdSpecificToolStateManager
attempt to convert whole DICOM data sets into json file to allow for restoration of image and tools entirely from json file. File was too large and caused computer lagging and crashing.
Analysis of Deep-Health Annotate's tool state restoration resulted in realization that labelmap may be the sticking point for this due to size.

Additional notes will be added as this task is researched.
