Panan Configuration - switch executables

[helenmacdonald]

We have been compiling a list of items that need considering in the Panantarctic configurations. At the request of @dougiesquire, I am moving some of the less urgent items to a different issues so they don't confuse the alpha release "todo" list.

We need to switch to a released executable. This is currently blocked as ISF - specific changes need to be incorporated into the released version see here and here for details.

Currently the configuration in question is awaiting PR to be merged but eventually will be sitting here.

@helenmacdonald thanks for adding this, can you please add these items to the project board etc, see issue template (or this example) for the checklist. I think this item is p1 as it's not needed for the alpha release.
