### Is your feature request related to a problem? When using Version 1.4.2 and attempting a merge of a delta table after having dropped a feature with external tooling, I get the following error: ` _internal.CommitFailedError: Unsupported table features required: [Unknown("checkpointProtection")] ` checkpointProtection is described in the links below, and it would be great if we could still read/write tables with checkpointProtection enabled... I can't find any reference in the delta-rs documentation around checkpointProtection. [Link 1: Protocol RFC](https://github.com/delta-io/delta/blob/master/protocol_rfcs/checkpoint-protection.md) [Link 2: Databricks DOC Description]( https://docs.databricks.com/aws/en/delta/drop-feature#-what-is-the-checkpointprotection-table-feature) ### Describe the solution you'd like checkpointProtection supported in read and write modes ### Describe alternatives you've considered _No response_ ### Priority Medium - Would be helpful ### Additional context _No response_ ### Contribution - [ ] I'm willing to submit a pull request for this feature - [x] I can help with testing this feature - [x] I can help with documentation for this feature
