libdx4 binary package in Ubuntu Bionic arm64

 Data Explorer is a system of tools and user interfaces for visualizing data.
 In general terms the visualization of data can be considered a 3-stage
 process:
    1. Describing and importing data
    2. Processing the data through a visualization program
    3. Presenting the resulting image.
 This is the package containing the shared libraries. Programs that use
 routines from the OpenDX classes usually depend on it.
