Add Shuffle Functionality

[liamharper2453]

Hi,

Initially added this PR to the main repo but see it's no longer actively developed.

This PR aims to add shuffle functionality to Orchestrator.

Shuffle:

• Adds a 'Shuffle' button to the right of the 'Play' button.
• When clicked it will randomly choose a song based on the ids provided from the Google Drive CSV. It will then continuously play random songs until stopped (a playlist of random songs is generated on click of the 'Shuffle' button which is then iterated through).
• Some FFXIV songs repeat endlessly while some do not and only loop once (i.e. 'Victory!').
• For songs that only loop once I found the pointer that I believe represents the games music buffer. I have added logic that skips to the next song when the buffer is no longer being written to i.e. when the first song loop ends.
• For songs that repeat endlessly I have simply added logic to change song after 3 minutes. Future work would be trying to find in-memory where the flag to repeat a song is stored.
• Shuffle can be toggled off by either clicking 'Stop' or 'Play'.

Hi, thanks a bunch for this PR! I see you've put a lot of work into it. I am definitely going to incorporate this into Orchestrion in some way or another, but it may not be exactly how you've done it here. For example, the 3 minute timer is not an acceptable way of ending a song in my opinion. I would prefer to research a method that works even if a song does not "end." In addition, I am not sure if you've tested this with Penumbra running - Penumbra is a modding plugin that disables audio streaming on startup in order to allow for audio modding. The music buffer location you've found may not be written to with streaming disabled. These are just my initial thoughts on this - like I said, I do appreciate the PR.
