Providing Arch64 image on Dockerhub

[pramodk]

Hello Team,

A long time Darshan user and I truly appreciate the functionalities provided by the dxt-explorer.

I see that on Dockerhub only x86_64 image is uploaded. Could you also push Aarch64 image as well? It would be handy!

By the way, I try to build the image from main branch and I got:

$ docker run -it hpcio/dxt-explorer -- dxt-explorer
Traceback (most recent call last):

    check_version(ffi, libdutil)
  File "/usr/local/lib/python3.10/dist-packages/darshan/discover_darshan.py", line 69, in check_version
    raise DarshanVersionError(
darshan.discover_darshan.DarshanVersionError: This version of PyDarshan requires libdarshan-util 3.4.4, but found 3.4.6

I changed Darshan to v3.4.4 to build the image locally.
