Save audio and text to files

Created by: batistasilva

Some features I've added in my version that I think will be important for one type of person. Added features to write a text file, which will be translated, as well as write the same to the translated text. Save tts stream in a file with .mp3 extension. Sequential file if necessary. It will depend on the size of the stream for the read content. Lets you define a new location to save files in the general menu. It also lets you define a custom name for the file. Everything has been tested on linux 12 bookworm. I have no way to test on mac or windows system.
