[功能] Deepl 的 API 是否可以自定义？

Preamble: Please read the User Guide and the project project in detail, and search for keywords related to your issue in the Issues. It is very likely that the feature you want has already been implemented, is in the planning stage, or has been proposed by others. CopyTranslator has been iterated many times, and its features are becoming more and more rich (complex). Without reading the full user guide, it is impossible to fully utilize its functions. If you have read the above content and determined that the feature has not been implemented or is not planned to be implemented. You are very welcome to continue the work below and request the addition of new features.
