[PATCH v2 0/5] builtin/repo: include largest object information

Greetings,

The "structure" output for git-repo(1) currently provides count information for references/objects as well as total inflated/disk sizes of objects by type. Info regarding the largest individual objects in the repository is not yet collected, but would be useful to users wishing to identify such large objects.

This patch series adds the following data points:
- The OID and size of the largest objects by object type
- The OID and parent count of the commit with the most parents
- The OID and entries count of the tree with the most entries

Changes from V1:

- Avoided duplicating the annotation string by handing over ownership.
- I decided to leave the `struct object_stats` structure alone for now
  as storing the various object values per-type does make it convenient
  to calulate the various totals. I may revisit this in a future series
  though.

Thanks, -Justin
