MB-System PDAL - mbio (ro) driver update

[epifanio]

Is your feature request related to a problem? Please describe.

The Point Data Abstraction Library (PDAL) offered a read-only driver for MB-System - I found it quite helpful in my workflow to extract angular response curves and geomorphometric features directly from sonar data. I loved it and loved the way how was possible to pipe SONAR data into a python based processing pipeline.

Unfortunately, starting with MB-System >5.7.5 (5.7.5 works with ubuntu 20.04 and PDAL master) - for MB-System greater than 5.7.5, the PDAL MBIO driver builds without error, but when attempting to run - it fails to initialize.

However, the pdal-mbio plug-in stopped working since MB-System 5.7.6 was released - I tried to debug the problem but failed; I also received some help from PDAL developers, but without success, as it requires someone with knowledge of MB-System internals to get this solved. There is a ticket open onPDAL; see #3791

Describe the solution you'd like
A collaborative effort between PDAL and MB-System to bring the mbio-dal reader back to life

Describe alternatives you've considered
The plug-in can still be used/tested adopting a specific version of ubntu+mbsystem+pdal - the combination that worked for me is:

• MB-System 5.7.5
• ubuntu 20.04 (pinned version of ubuntu as MB-System 5.7.5 no longer build on newer ubuntu version, see #1262
• PDAL Master
  I have prepared a docker image to replicate a working solution - it includes a development environment (e.g., to build MB-System and PDAL)

docker pull epinux/pdal-mbio:mbio-5.7.5

Additional context
The MB-System -- PDAL MBIO driver was previously founded by the US Army Corps of Engineers - USACE - I didn't try (yet) to contact them to see if they are willing to look into this.
