Feature/elevenlabs - Shrinked MVP

[HackXIt]

Due to lack of time and doing the programming alone, I have completed a very basic version of the application.

It is capable of the following:

• Configure settings for an API (ElevenLabs)
• Store or load settings from app_settings.json (Stored in same folder as executable)
• API can be selected from settings and application settings as well as API specific settings are accessible globally
• Load a text file into the editor
• Save a text file from the editor
• Generate a .wav audio file by calling ElevenLabs API using the input text
• Write README on how to contribute additional APIs with settings integration

The application is still error-prone, due to the early stage of development.

Hopefully others will find my READMEs helpful in continuing the project for contribution.

What doesn't work:

• Audio control buttons (Start, Stop, etc.)
• Listen button (Livestream audio instead of saving to file)
• SSML insertion (although some backend functionality is available to do so)
