sherpa-onnx-offline-tts: Allow piping text using cat or text file input with command line parameter

[domasofan]

Hi all,

Is it possible to add the possibility to pipe text into the tts engine using cat or a command line parameter?
That would help greatly when converting large amounts of text into speech.
Especially blind people might be interested in that feature.

Greetings and thanks,
Simon

It might be a good idea to provide both. text input through stdin and also through a command line parameter.
