feat: Add reset and copy methods to datatypes

This change adds a `reset()` method to the `AtomicField`, `SimpleField`, `Coordenadas`, and `GerarPlai` datatypes. The `reset()` method removes the `value` attribute from the instance, allowing it to be reused. Additionally, a `copy()` method has been added to return a new instance of the datatype.
