Currently, the OpenZeppelin Wizard for Stellar (https://wizard.openzeppelin.com/stellar) generates contracts that use default_impl attribute to implement all trait functions, when possible.

Suggestion is to add a UI toggle to choose between:

• Using the #[default_impl] attribute (could be the default option)
• Generating explicit implementations of all trait functions
