Support Swift Package Manager

Is your feature request related to a problem? Please describe.
We set up a Capacitor app with SPM instead of Cocoa pods. Therefor this library doesn't work for us.

Describe the solution you'd like
A Package.swift file/ SPM support

For now i forked this library and somehow managed to get this working, but honestly I don't feel super safe about it, as I also had to mess with SQLCipher. Links I followed:

• Swift Package Manager Support sqlcipher/sqlcipher#371

@marius-se Do you mind sharing your fork? Would offer a good starting place for investigating this feature.
