d2l-labs-ou-filter

A Lit component that renders org unit structure tree. It supports load more and searching functionality.

Note: this is a "labs" component. While functional, these tasks are prerequisites to promotion to BrightspaceUI "official" status:

• [ ] Design organization buy-in
• [ ] Architectural sign-off
• [x] Continuous integration
• [x] Cross-browser testing
• [x] Unit tests (if applicable)
• [x] Accessibility tests
• [x] Visual diff tests
• [x] Localization with Serge (if applicable)
• [x] Demo page
• [x] README documentation
