Add OpenJPH (#14824)

[OpenJPH](https://github.com/aous72/OpenJPH/) is a widely used library
that implements High-Throughput JPEG 2000. It is, for example, a
dependency of the [OpenEXR
Library](https://github.com/AcademySoftwareFoundation/openexr). It was
suggested that OpenJPH, as building block of many other libraries,
should be tested independently.

The primary maintainer of [OpenJPH](https://github.com/aous72/OpenJPH/)
is @aous72.
