universal viewer is broken

Bug Description

When I click on UV tab in the visualizer, the viewer doesn't

1. show video
2. show timeframe-based annotation

Instead it shows an error "Unable to load manifest"

Reproduction steps

1. open a MMIF with TimeFrame annotations
2. click UV tab next to the default html video player

Expected behavior

1. video show up in the UV player
2. UV viewer provide "jump" interface for timeframe annotations

Log output

34 includes fixes for the problems mentioned above. However, after working on this, I decided to take the UV down for now, primarily because the current UV implementation or ours doesn't provide any additional features/value to us.

• the only annotation type on which IIIF manifest conversion works is TimeFrame (and their label) but the same functionality does exists as Thumbnail tab. https://github.com/clamsproject/mmif-visualizer/blob/91cec330455435f4d47800076f2f9badd5c9ec02/utils.py#L194-L197
• then, even the only conversion has been disabled from the very beginning of the integration UV into mmif-viz, anyway https://github.com/clamsproject/mmif-visualizer/blob/65cb32ad9c9d8b9ec0fd46ff07da994e8f9f7d37/iiif_utils.py#L122-L160

For the future, we can work on a "consumer" for targeting more general conversion between MMIF and IIIF, but I don't necessarily think that has to be "integrated" into mmif-viz.
