feat: added voicechat recording primitive

[personcopperfine]

Adds a primitive for recording a player's voice chat for content moderation (using AI transcription for said words or human review for example).

A basic rundown is that the game supports multiple codex, in older source titles sv_voicecodec controlled it, I'm assuming modern CS2 is using 48,000 with 1 mono channel. libopus is included in the sniper SDK but windows requires edits for visual studio code.

enum VoiceDataFormat_t {
	VOICEDATA_FORMAT_STEAM = 0;
	VOICEDATA_FORMAT_ENGINE = 1;
	VOICEDATA_FORMAT_OPUS = 2;
}
