Update to h5web v7
This MR updates daiquiri to h5web v7 with the almost "minimal" required changes (i.e., no refactoring to simplify much daiquiri like removing SvgScene
or LinearVisCanvas
).
See release notes for details on h5web v7 breaking changes: https://github.com/silx-kit/h5web/releases/tag/untagged-ac888766580ceb01abd9
It still needs some testing.
