Investigate if opening a store with icechunk 0.1.0-alpha15 corrupts a store written with alpha12

[abarciauskas-bgse]

@sharkinsspatial @maxrjones - I am just tagging you on this as an FYI since I asked you to review earth-mover/icechunk-nasa#4

I noticed upon testing today that the MUR SST icechunk store I created and previously demonstrated as working in https://github.com/earth-mover/icechunk-nasa/blob/main/notebooks/read_virtual.ipynb has been corrupted in someway. It's unclear when and how (I had an inconclusive slack conversation with Seba about this), and my only guess is that opening the store with a later version than it was created with somehow corrupts the data. Seba did confirm that the on disk format changes between pre-stable release versions (such as alpha12 and alpha15)

You can see the traceback for the error IcechunkError: store error: unsuccessful session operation: Repository error: error contacting storage error getting object from object store service error`` in this gist: https://gist.github.com/abarciauskas-bgse/ddfb19f02f3018df191c9ec8ade67765.

I'm not sure it's worth the time, given I think icechunk is nearing a stable release, but it would be nice to investigate in a toy example if my guess is correct and that reading with a later version corrupts the store.
