[Feature] Replace Spoken Language Identification with MediaPipe Solutions

[AmitMY]

Problem

The current spoken language identification - implemented in #10 - has limitations, specifically, it struggles with short texts

Description

The MediaPipe Language identification does not suffer from the same limitations. It is also smaller in size (315kb compared to 1.1mb).

We can replace the current spoken language identification, or better yet, allow for options in the settings.

Alternatives

Keep the current identification. For spoken language change recommendation, don't show the suggestion until the text is "long enough"
