Extend Datasets getDownloadSize API endpoint to support file search criteria and deaccessioned datasets

+Extended the getDownloadSize endpoint (/api/datasets/{id}/versions/{versionId}/downloadsize), including the following new features:
+
+- The endpoint now accepts a new boolean optional query parameter "includeDeaccessioned", which, if enabled, causes the endpoint to consider deaccessioned dataset versions when searching for versions to obtain the file total download size.
+
+
+- The endpoint now supports filtering by criteria. In particular, it accepts the following optional criteria query parameters:
+
+  - contentType
+  - accessStatus
+  - categoryName
+  - tabularTagName
+  - searchText

+
+Filtering by search text is also optionally supported. The search will be applied to the labels and descriptions of the dataset files, to return the size of all files available for download that contain the text searched in one of such fields.

+Usage example:
+
+.. code-block:: bash

+File access filtering is also optionally supported. In particular, by the following possible values:
+
+* ``Public``
+* ``Restricted``
+* ``EmbargoedThenRestricted``
+* ``EmbargoedThenPublic``
+
+If no filter is specified, the files will match all of the above categories.
+
+Please note that filtering query parameters are case sensitive and must be correctly typed for the endpoint to recognize them.
+
+By default, deaccessioned dataset versions are not included in the search when applying the :latest or :latest-published identifiers. Additionally, when filtering by a specific version tag, you will get a "not found" error if the version is deaccessioned and you do not enable the ``includeDeaccessioned`` option described below.
+
+If you want to include deaccessioned dataset versions, you must set ``includeDeaccessioned`` query parameter to ``true``.
+
+Usage example:
+
+.. code-block:: bash
+
+  curl "https://demo.dataverse.org/api/datasets/24/versions/1.0/downloadsize?includeDeaccessioned=true"
