Support for . name spacing in field object name

[tomjamesallen]

I've been trying to get codegen up and running with the Sanity Connect for Shopify starter and I'm running into some issues. Some of the object definitions contain periods to namespace fields e.g. seo.singleton. When used to create type names this is throwing a syntax error.

Is it possible to add support for converting . in field names to an underscore or dropping it all together to avoid this issue?
