Build modified streamline images

The official image from streamline does not currently work for the arm64
platform. As a temporary measure, the source code and docker build scripts
have been lifted from the official images and are used to build locally.

Some additional modifications are made to reduce overall image size, these
are documented in docker/README.md

+ * This feature plug-in for DataTables adds page length control links to the
+ * DataTable. The `dom` option can be used to insert the control using the `L`
+ * character option and it uses the `lengthMenu` options of DataTables to
+ * determine what to display.
+ *
+ * @example
+ *   $('#myTable').DataTable( {
+ *     dom: 'Lfrtip'
+ *   } );
+ *
+ * @example
+ *   $('#myTable').DataTable( {
+ *     lengthMenu: [ [10, 25, 50, -1], [10, 25, 50, "All"] ]
+ *     dom: 'Lfrtip'
+ *   } );
