Review Comment:
`SchemaV1` (and `SchemaV2`) are internal structs and are not visible to a
user of the library. `SchemaV1` is just used for serialization/deserialization.
We can still do your recommended conversion.
The only publicly visible struct for a schema is the `Schema` struct, which
has the same representation for v1 and v2 tables.
