Detect wasm version

[alextekartik]

Yes the intention is to be backward compatible as much as possible and yeah bug might happen but since the developer should see a relevant exception in this case while developing, I'm perfectly fine in having him manually update the wasm binary when he sees obvious crashes. I guess you might have similar issue with drift on the web. Closing the issue, thanks.

The intention was for changes to be backwards compatible, so it looks like I've slipped up here -- sorry!

I think we can provide the expected version as a constant in the library - you can get the actual version through CommonSqlite.version and compare them.

So I've just realized that this wouldn't work of course since the error happened when instantiating CommonSqlite -- oops! I think the original problem can reasonably be considered a bug in this package since we should support older versions in general. That was fixed in 4d4251d.

The desired behavior in this package is to throw an exception suggesting a upgrade for sqlite3.wasm when an unsupported feature is used, but to generally work with older versions of the compiled library. That's also the intention that you had for the sqflite wrapper, right? Do you still need an API to check the expected version if older versions are supported?
