Allow using SQLite extensions

[CaptainDario]

Is your feature request related to a problem? Please describe.
I have been using your package in production already for some months and it has been awesome and just works great, thank you so much!
Currently, I am thinking of a way for a user to synchronize his SQLite database between devices. While researching, I stumbled upon this package cr-sqlite.
When searching the docs I found the supported extensions but I could not find a way to load runtime extensions. Therefore, I am interested in the ability to load runtime SQLite extensions using this package.
If this is already possible, I am sorry for the inconvenience.

Describe the solution you'd like
A way to load and execute SQLite runtime extensions.
database.extension("cr-sqlite").run("SELECT crsql_as_crr('table_name')")
