Allow setting maxIssuerNumber for Twint via Drop-In configuration (#…

…1913)

# Summary
- The `maxIssuerNumber` for Twint can now be set when using Drop-In
- Statically linking the `TwintSDK` to prevent name clashing when using
another library that includes the `TwintSDK` as well (e.g. Datatrans)

# Release notes
