I think adding a `Long` or `Optional<Long>` to the
`org.apache.spark.sql.connector.catalog.Identifier` interface could work for us:
```
static Identifier of(String[] namespace, String name, Long version) {
return new IdentifierImpl(namespace, name, version);
}
...
Long version();
```
Until the change to this interface makes it into a released Spark 3 version,
we could add this extension to Iceberg and use this internal extension of
`Identifier` to load the table with the snapshot id, when reading it using
`.option("snapshot-id", ...)` or `.option("as-of-timestamp", ...)`. When a
Spark version is released with this change to `Identifier`, we can switch from
our internal extension to the upstream `Identifier`.
