Archive current env and test reading `.pkl` files from new MAAP ADE

.pkl files can only be read by the same environment that generated them #50. July 31st, MAAP will migrate to a new ADE that includes different base envs in both the ADE and DPS. This means that it's possible that the migration to the new ADE will lock us out of our own files. To prevent this, we need to:

• Archive the env we are using to write out files now, so that we can default back to using it if necessary
• test that the files can be read on the new ADE at ade.maap-project.org

changed due date to July 28, 2023

@greg you volunteered to put in a request with the MAAP team to get an image that we could test on the new ADE.

I tested on the new ADE. Seemed to be able to read files from the env I had built on the old ADE.
