New feature: declare function schema

[mattiarossi]

Hi, progressing with the use cases for plv8ify, I'd like to add another decoration to allow creating the functions in a specific schema. Right now we're working around this by using prefixes, but it is sub optimal, as we either need to break down the code by schema, or create different scripts in the ci for them.

Would a decoration style like

//@plv8ify-schema <my_custom_schema>
export function my_test() {
  return "test";
}

be acceptable? In this case the generated SQL would be something like:

CREATE OR REPLACE FUNCTION my_custom_schema.my_test() 
...
