feat: add "Maximum" quality option

[ohslyfox]

Motivation

When a user selects a specific quality (e.g. 1080p60) and then swaps to a stream that doesn't offer that exact option (e.g. only has 1080p), the saved quality no longer matches any available option. This causes the player to silently fall back to Auto

Summary

• Add passthrough quality option that resolves to the max bitrate quality
• Add defensive sort on quality response payload to guarantee functionality
  • Example payload:

{
  "name": "1080p60",
  "group": "chunked",
  "codecs": "avc1.64002A,mp4a.40.2",
  "bitrate": 7075829,
  "width": 1920,
  "height": 1080,
  "framerate": 60,
  "isDefault": true,
  "variantSource": "source",
  "variantId": "",
  "attributes": {
    "Pipeline": "",
    "SourceType": ""
  },
  "sourceGroups": []
}

I don't like that the main menu displays the active quality (e.g., "1080p60") rather than "Maximum" when max quality is selected. It creates a situation where the user doesn't know they have max quality selected unless they open the quality settings menu. Additionally, I prefer the word "Best" to describe the best possible quality over "Maximum".

Can you address these issues?

It creates a situation where the user doesn't know they have max quality selected unless they open the quality settings menu.

I considered this, but the alternative would display "Maximum" with no indication of what the actual quality selection is.

Agreed with "Best" terminology, maybe we can include the quality in parenthesis like Best (1080p60) since "Best" saves on width space. What do you think?

Works for me, go for it!
