Manifest inspect

To experiment, I did

import icechunk as ic
import xarray as xr

storage = ic.s3_storage(
   bucket="icechunk-public-data",
   prefix="v1/era5_weatherbench2",
   region="us-east-1",
   anonymous=True,
)

repo = ic.Repository.open(storage=storage)
manifests = repo.lookup_snapshot(repo.lookup_branch('main')).manifests
json.loads(repo.inspect_manifest(manifests[-1].id))

{'id': 'ZSBZ88JV8HKHNRQBYM40',
 'size_bytes': 455624,
 'total_chunk_refs': 8760,
 'arrays': [{'node_id': 'SQDGS52B4TAWG', 'num_chunk_refs': 8760}]}

Some comments:

1. repo.inspect_manifest gives me a string. Since we are returning json, can we use json.loads on the python side?
2. Even with that, as a user, this is less useful because I don't know what array the NodeId refers to, can we add the path too?
3. As a user, I think i'm more interested in looking up the manifests for a particular array. So perhaps we need repo.lookup_manifests("path/to/array", snapshot_id=repo.lookup_snapshot('main')) -> list[ManifestInfo] or perhaps a full summary (total nbytes, total refs, num of manifests, list[manifestInfo])`.
