Bulk Add filter to data selection feature

[juliangruendner]

The filter of data selection features should be extended to support bulk adding filter by terminology and code.

To switch to this next to the search bar a drop-down should be added which allows switching between
(search, bulk-search), where search is the default as one accesses the filter tab

If bulk search is selected search bar should be replace by

A dropdown for all the available terminologies for the particular search
A text field the user can enter codes comma separated
A button to search and add the filter

if the button is "search and add filter" is pressed the ui should search using the input terminology + List_of_codes
e.g. loinc.org + [718-7, 38735-7, ...]

Based on this input the UI should search for each code and select it as filter for the feature
A filter should only be added if its code is an exact match to terminology+code
An extra list should be shown to the user below the filter with all the codes which could not be found.
