Called on an already-open connection: DoltLite clones into the connection's
own database.
Usage
dolt_clone(con, url, lazy = FALSE)
Arguments
- con
a `DoltliteConnection`.
- url
the source URL.
- lazy
install refs and record `origin` without copying the reachable
chunk graph, fetching chunks on demand instead. To reopen a lazy clone in
another process, pass `dbname` as
`"file:/path/to/db?lazy_origin=1"` with `flags` including SQLite's URI
bit.
