Save folder selectable

[Gzushgshsh]

The idea I had is to have 3 options:

1 - Save in internal storage (the way the app currently does)

2 - Save in external storange (With the same current directory organization but on the SD Card)

3 - Select a folder to save contents (Open a folder picker that lets the user select any folder)

🤔What do you think?

我的手机没有外部SD卡，所以我无法测试

即使没有SD卡，SD卡的路径也可能在AOSP中包含的文件管理器中自己分配，所以你只需要实现第一个路径。

我可以实现选择自定义目录
