Refactor to vz2 and ic1

[jbusecke]

Replacing #7 due to the inability to get secrets for fork PRs (discussion and tasks listed over there).

• Closing Refactor MUR SST lambda app to icechunk v1 and virtualizarr v2 #3 Document uv+jupyterlab workflow #10 Proposed testing strategy for this repo and beyond #11 Removing old code related to subscriptions #9
• I assume this will close Deployment Issue: Time continuity failed #6 and Hitting decompression error in local tests #8, but we need to deploy and wait a bit to confirm
• I just noticed that uv is maintaining a bunch of pre-commit hooks. I should probably prefer these over my custom stuff!
• I want to explore if persisting the config to storage makes sense in this contex (I will test this on a synth example but would be applied to a potential rewrite of the store) -> The icechunk is persisted to storage by default (I have added a tiny test to ensure that stays the same way going forward)
  • Depending on the findings here, I could raise an issue on vz to add a 'persist_to_storage' flag to vds.vz.to_icechunk.
