How does it work under the hood?

1. It determines whether the provided AST node type is related to [Svelte] syntax only.
1. Based on node's type check from above:
- it uses either this package's printer to print [AST] node related to [Svelte] syntax,
- otherwise it uses [esrap] to print [ESTree] specification-complaint [AST] node.
