[NoahBres]

https://github.com/acmerobotics/ftc-dashboard/issues/81 POC for custom background image for Field View:

Changes still needed:

• Branched from bump deps
  • https://github.com/acmerobotics/ftc-dashboard/pull/92
• View specific storage API:
  • See: https://github.com/acmerobotics/ftc-dashboard/issues/95
  • Current POC just uses a really naive way to set local storage. Is not able to clear local storage items when views are deleted from ConfigurableLayout
• Proper error handling

Uh oh. I seemed to have irreparably messed up this PR. I meant to change the base to NoahBres:bump-deps but I pattern-matched a completely different branch. Now I can't modify the base or reopen the PR 😢
