Use upstream freeopcua

[cjue]

Hi, thank you for your effort towards this project!

Is there a specific reason to reference your own fork of freeopcua instead of the upstream version? My suggested patch would be this:

diff --git a/.gitmodules b/.gitmodules
index 9231295..798a59d 100644
--- a/.gitmodules
+++ b/.gitmodules
@@ -1,6 +1,6 @@
 [submodule "ros_opcua_impl_freeopcua/freeopcua"]
        path = ros_opcua_impl_freeopcua/freeopcua
-       url = git@github.com:iirob/freeopcua.git
+       url = https://github.com/FreeOpcUa/freeopcua.git
 [submodule "ros_opcua_impl_python_opcua/python-opcua"]
        path = ros_opcua_impl_python_opcua/python-opcua
        url = https://github.com/FreeOpcUa/python-opcua.git

Using the https version for the remote is better for machines without github ssh keys set up.
