[3.9-PS] Support for Presentation States and GSPS Export: Support rendering presentation states and exporting as GSPS files

[sedghi]

What feature or change would you like to see made?

• Implement support for rendering and displaying presentation states within the OHIF viewer
• Introduce functionality to set display areas and apply presentation state annotations
• Leverage existing building blocks from Cornerstone 3D, such as setViewReferenceand setViewPresentation
• Develop a user interface (UI) for exporting the current viewer state as a GSPS (Grayscale Softcopy Presentation State) object
• Integrate the ability to save and export presentation states as GSPS files
• Explore potential use cases and workflows involving presentation states, such as sharing viewer configurations or annotated views

More info:

GSPS has the study, series, and frame number reference, along with meta information about window leveling, rotation, display view area, and drawing lines, among other features. Currently, we possess all the necessary building blocks, and special thanks go to @wayfarer3130.

We require a user interface for exporting as well. To enable users to choose which set of features should be exported, we can provide some default options and give additional choices for the remaining features.

Why should we prioritize this feature?

Presentation states and GSPS export capabilities are essential for standardized sharing and communication of viewer configurations, annotations, and display settings. By supporting presentation states, OHIF can facilitate collaboration and consistency in image interpretation workflows, particularly in clinical and research environments. This feature aligns with OHIF's goal of providing a comprehensive and interoperable medical imaging platform.

It would be great if this includes support display of Graphic Annotations, since there are a lot of them out there.

@rbartonmedweb can you provide us some samples?
