Rationale for this change

Adds support for the RollingManifestWriter to split large commits into multiple manifest files instead of one giant file. This PR wraps the ManifestWriter and follows the Java implemenation of checking the size every 250 entries. The bulk of this work was done in #650.

Next step is wiring this into fast_append, but it's also useful for manifest repair operations, like deduplicating entries and rewriting manifests without blowing up the output sizes
