Use packages to find mesh at run time

Hello Using packages instead of find makes the package searched in runtime and not at the compilation stage. Thanks to this, you can run visualizations on remote equipment where the file path is different. Regards

@Serafadam Can I ask you for review?

Hi @rafal-gorecki, this change was introduced in recent commit https://github.com/luxonis/depthai-ros/pull/511, as I don't have the setup to verify this, could you present the case where it doesn't work currently? Also tagging @Nibanovic to the discussion.
