Use Vec for field MetaData::other

Browse source 
by using `tuple_vec_map` to make the `Vec<(CompactString,
serde_json::Value)>` appears as a map.

This is OK because we don't access that part anyway and only add such
field to avoid losing any information when deserialize, modify it and
serialize it again to overwrite existing metafile.
