Does not use @libsql/client for local files

[netroy]

Hi,

I just started evaluating libSQL as an alternative to SQLite, and started with this package.
But, when I tried to make my test application work without the sqlite3 package, I realized that for local files, the sqlite3 package is used.

I notice now that this is mentioned in the ReadMe, but I think something like this needs to be higher up in the ReadMe, and highlighted better, as many people who use sqlite3 do so with local files, and for them, this isn't really a drop-in replacement.
