* [Fixed] Keep setting option for the voice
- It was always changed to the first available voice
- Also added an error if the selected voice isn't valid
* [Fixed] elevenlabs_tts API key handling
- The one from the settings wasn't applied
- We always got "Enter your API key", even when the settings specified
an api_key
* [Added] elevenlabs_tts model selection
- Now we can also use the "eleven_multilingual_v1" model.
Used for anything but english.
Reworked remove_surrounded_chars() to use regular expression ( https://regexr.com/7alb5 ) instead of repeated string concatenations for elevenlab_tts, silero_tts, sd_api_pictures. This should be both faster and more robust in handling asterisks.
Reduced the memory footprint of send_pictures and sd_api_pictures by scaling the images in the chat to 300 pixels max-side wise. (The user already has the original in case of the sent picture and there's an option to save the SD generation).
This should fix history growing annoyingly large with multiple pictures present
