WIP Build using preinstall and prebuild hooks

Currently : submodules install and build are done before building and
installing the main project.

Touching a file in a submodules triggers main project rebuild. But does
not seem to rebuild the submodule.

Also the built package is buggy : there is an error while creating the
annotation window

build_deps.sh

 #!/bin/bash
-cd mirador-video-annotation
-docker run --rm -v $PWD:/opt -it node:12 /bin/sh -c "cd /opt && npm install && npm run build:es"
-cd ../annotations-plugin
-docker run --rm -v $PWD:/opt -it node:12 /bin/sh -c "cd /opt && npm install && npm run build"
+declare -A SUBMODULES=(
+    ['mirador-video-annotation']="build:es"
+    ['annotations-plugin']="build"
+)
+
+run_on_modules(){
+    for mod in "${!SUBMODULES[@]}"; do
+        echo -e "\t$mod"
+        cd $mod
+        if [ "$1" == "install" ]; then
+            npm install
+        else
+            npm run ${SUBMODULES[${mod}]}
+        fi
+        cd ..
+    done
+}
+
+if [ "$1" == "install" ]; then
+    echo "Installing submodules"
+    run_on_modules install
+fi
+echo "Compiling submodules"
