feat: Inbuilt mp3 player

[roerohan]

• Uses ffmpeg and speaker to play mp3 from stream
• Player is now abstract, AudioPlayer and VideoPlayer implement it.
• play() function returns a Player object.

Issues

• sudo apt-get install libasound2-dev is needed on Ubuntu/Debian operating systems for npm install to succeed
• Include ffmpeg binaries
• Write a script to check if libasound2-dev is present, if not, prompt the user or install it.
• Catch syntax error for invalid json.

[roerohan]

CI/CD npm test fails due to some ALSA error.
@thebongy , how can we fix this?

TODO:

• Include ffmpeg binaries.
• Catch syntax error for invalid json.

[thebongy]

Need some updates in the README about node-gyp deps on windows

[roerohan]

TODO

• README.md still has to be updated. @thebongy

Done

• Added progress bar only for CLI.
• ESLint accept extraneous dependency since node-speaker is in optionalDependencies.

We'll update the README in the next version, I have added basic information.
