feat: ability to disable HLS subtitles by default

[ryparker]

Current Behavior

Subtitles are loaded by default.

Expected Behavior

Ability to configure wether the subtitles should be enabled by default or not.

Steps to Reproduce

1. Render the ReactPlayer with this Senate floor livestream URL: https://www-senate-gov-media-srs.akamaized.net/hls/live/2096634/stv/stv022924/master.m3u8 (note this livestream will be disabled after it ends)

Environment

• URL attempting to play: https://www-senate-gov-media-srs.akamaized.net/hls/live/2096634/stv/stv022924/master.m3u8
• Browser: Brave (Chromium)
• Operating system: Sonoma MacOS
• jsFiddle example: Just open the demo site (https://cookpete.com/react-player/) and use the provided HLS stream.

Other Information

I've only encountered this with this particular HLS. It must be something that the host is configuring on the stream. However I still expected to have the ability to override the subtitle defaults on the player/UI side.
