We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
romanized decorator mutates ROMANIZATION_DICT
After `@romanized` is used, ROMANIZATION_DICT gets updated and every module importing it will get this mutated ROMANIZATION_DICT.
Snippet below should reproduce problem.
```
from mimesis import decorators, data


if __name__ == '__main__':
    print('ROMANIZATION_DICT: before')
    print(data.ROMANIZATION_DICT)

    @decorators.romanized('ru')
    def russian_name(): return 'Петр Петрович'
    # next line is where ROMANIZATION_DICT mutates
    russian_name()

    print('ROMANIZATION_DICT: after')
    print(data.ROMANIZATION_DICT)
```
Problem is here:
https://github.com/lk-geimfari/mimesis/blob/master/mimesis/decorators.py#L29
