feat: Add Static WADO display (#2499)

* Rebased to have just the static view changes

* Changes based on the PR

* Couple more changes for the PR

* Removed an extraneous log

* Fix the study worklist display when returning to the page

* Added some documentation on the static wado data source setup, and a
bounds check change on the Queue test which was failing

* PR updates - change the undefined study description to '' and remove the aws deploy

* Fixed the e2e tests to actually pass/fail correctly on actual results

+## Static Files
+
+There is a binay DICOM to static file generator, which provides easily served
+binary files.  The files are all compressed in order to reduce space signifcantly,
+and are pre-computed for the files required for OHIF, so that the performance
+of serving the files is just the read from disk/write to http stream time, without
+any extra processing time.
+
+The project for the static wado files is located here:
+[static-wado]: https://github.com/wayfarer3130/static-wado
+
+It can be compiled with Java and Gradle, and then run against a set of dicom,
+in the example located in /dicom/study1 outputting to /dicomweb, and then a
+server run against that data, like this:
+```
+git clone https://github.com/wayfarer3130/static-wado.git
+cd static-wado
+./gradlew installDist
+StaticWado/build/install/StaticWado/bin/StaticWado -d /dicomweb /dicom/study1
+cd /dicomweb
+npx http-server -p 5000 --cors -g
+```
+
+There is then a dev environment in the platform/viewer directory which can be run
+against those files, like this:
+```
+cd platform/viewer
+yarn dev:static
+```
+
+Additional studies can be added to the dicomweb by re-running the StaticWado command.
+It will create a single studies.gz index file (JSON DICOM file, compressed)
+containing an index of all studies created.  There is then a small extension
+to OHIF which performs client side indexing.
+
+The StaticWado command also knows how to deploy a client and dicomweb directory
+to Amazon s3, which can then server files up directly.  There is another
+build setup build:aws in the viewer package.json to create such a deployment.

+## Static WADO Client
 
+If the configuration for the data source has the value staticWado set, then it
+is assumed that queries for the studies return a super-set of the studies, as
+it is assumed to be returning a static list.  The StaticWadoClient performs the
+search functionality manually, by interpretting the query parameters and then
+applying them to the returned response.  This functionality may be useful for
+other types of DICOMweb back ends, where they are capable of performing queries,
+but don't allow for querying certain types of fields.  However, that only works
+as long as the size of the studies list isn't too large that client side
+selectiton isn't too expensive.
