RtViewerPlugin : similar to the StoneWebPlugin, but for the sole RtViewer sample

+RtViewerPlugin
+---------------
+This C++ plugin allows to extend the Orthanc Explorer to add a button labeled "Stone RT Viewer" 
+in the series page. 
+
+It also embeds and serves the RT Viewer files and is thus a standalone way of using this viewer.
+
+Please note that building this plugin requires that the RtViewer be built inside the wasm-binaries 
+folder of the repo.
+
+This will automatically be the case if you use the `<REPO-ROOT>/OrthancStone/Samples/WebAssembly/docker-build.sh` script.
+
+If you use the `build-wasm-samples.sh` script above, you will have the copy `RtViewer` **folder**
+from `<REPO-ROOT>/out/install-stone-wasm-RtViewer-RelWithDebInfo` to `<REPO-ROOT>/wasm-binaries/`.
+
+TL;DR: Build like this (assuming `~/orthanc-stone` is the repo ):
+
+```
+~/orthanc-stone/OrthancStone/Samples/WebAssembly/docker-build.sh
+~/orthanc-stone/OrthancStone/Samples/RtViewerPlugin/docker-build.sh
+```
+
+Once this is done, the plugin can be found in:
+
+```
+~/orthanc-stone/wasm-binaries/share/orthanc/plugins/libRtViewerPlugin.so
+```
+
+Add this path to the `"Plugins"` section of your Orthanc configuration, start Orthanc, and you 
+should now see a "Stone MPR RT Viewer" button in the Orthanc Explorer, at the *series* level.
+
+Open it on a CT series, and the RTSTRUCT and RTDOSE series of the same study will be loaded in
+the viewer.

+/**
+ * \mainpage
+ *
+ * This C/C++ SDK allows external developers to create plugins that
+ * can be loaded into Orthanc to extend its functionality. Each
+ * Orthanc plugin must expose 4 public functions with the following
+ * signatures:
+ * 
+ * -# <tt>int32_t OrthancPluginInitialize(const OrthancPluginContext* context)</tt>:
+ *    This function is invoked by Orthanc when it loads the plugin on startup.
+ *    The plugin must:
+ *    - Check its compatibility with the Orthanc version using
+ *      ::OrthancPluginCheckVersion().
+ *    - Store the context pointer so that it can use the plugin 
+ *      services of Orthanc.
+ *    - Register all its REST callbacks using ::OrthancPluginRegisterRestCallback().
+ *    - Possibly register its callback for received DICOM instances using ::OrthancPluginRegisterOnStoredInstanceCallback().
+ *    - Possibly register its callback for changes to the DICOM store using ::OrthancPluginRegisterOnChangeCallback().
+ *    - Possibly register a custom storage area using ::OrthancPluginRegisterStorageArea().
+ *    - Possibly register a custom database back-end area using OrthancPluginRegisterDatabaseBackendV2().
+ *    - Possibly register a handler for C-Find SCP against DICOM worklists using OrthancPluginRegisterWorklistCallback().
+ *    - Possibly register a custom decoder for DICOM images using OrthancPluginRegisterDecodeImageCallback().
