Filter thumbnails same as webclient

[will-moore]

See feature request at https://forum.image.sc/t/expected-behaviour-when-opening-an-image-in-iviewer/42571/2
and filtering discussion at ome/design#107

I assume that we want the current filtering state in webclient to be replicated in iviewer when you open an image from a filtered Dataset (even when/if you can save filtered state in webclient - we want the current (unsaved) filtering.
So we'd need to dynamically pass that to the iviewer when opening an image.

Currently, if you adjust the rendering settings in the preview panel of webclient, then choose to open that image in iviewer, the current rendering settings are passed in the query string.

However, we'd need to preserve the filtering params in the query string, even when we browse to other thumbnails in iviewer. Also need to take into account the filtering when calculating the total number of thumbnails to load and in the thumbnail lazy loading (pagination).
In that case, we'd have to use a different api (not the JSON /api/) to load thumbnails since we'd need the filtering to happen server-side.

This is relevant to the current limitations in webclient filtering and pagination (see https://forum.image.sc/t/paging-behaviour-in-thumbnail-parade/42573/1). So, a server-side filtering functionality is needed for both.
