fix: corrige suppl no nome do pacote sps e permite sufixo adicional (#1059)

* fix: corrige suppl no nome do pacote sps e permite sufixo adicional

- Create dedicated sps_pkg_name_suppl property to encapsulate supplement formatting logic
- Move supplement value transformation from sps_pkg_name to isolated method
- Handle special case where suppl=0 becomes 'suppl' string
- Format other supplement values with 's' prefix (e.g., 's1', 's2')
- Improve code organization and readability in package name generation
- Implement additional_sps_pkg_name_suffix as property with getter and setter
- Store value in private attribute _additional_sps_pkg_name_suffix
- Include additional suffix in sps_pkg_name composition
- Enable dynamic modification of package name suffix after instantiation

* fix: corrige referência indefinida de variável suppl em XMLWithPre

- Corrige bug onde self.suppl estava sendo usado em vez da variável local suppl
- Adiciona atributo _additional_sps_pkg_name_suffix ao __init__ da classe XMLWithPre
- O erro ocorria no método que determina o sufixo do nome do pacote suplementar
