Changing the playbackDuration of a resource, doesn't seek it

[stijnb1234]

Please describe the problem you are having in as much detail as possible:
When I use resource.playbackDuration = seek;, it doesn't seek the resource when I play it. It will just start playing at the beginning.

Include a reproducible code sample here, if possible:

const connection = joinVoiceChannel({
    channelId: channel.id,
    guildId: channel.guild.id,
    adapterCreator: channel.guild.voiceAdapterCreator,
});

const player = createAudioPlayer();

const seek = 5000; //Seek 5 sec

const resource = createAudioResource("./music.mp3", { inlineVolume: true });
resource.volume.setVolume(0.4);
resource.playbackDuration = seek;

player.play(resource);

connection.subscribe(player);

Further details:

• @discordjs/voice version: 0.5.6
• Node.js version: 16.6.1
• Operating system: Windows 11
• Priority this issue should have – please be realistic and elaborate if possible: Moderate

Relevant client options:

• partials: none
• gateway intents: GUILDS, GUILD_BANS, GUILD_MESSAGES, GUILD_MESSAGE_REACTIONS, DIRECT_MESSAGES, GUILD_MEMBERS, GUILD_VOICE_STATES
• other: none

playbackDuration is intended as a read-only property, changing it won't do anything.

This library does not yet support seeking, if you'd like to do it, you'd need to use FFmpeg or some other tool.

Ah, okay. Because it's not defined as readOnly in the code itself. :P

Here you indicate that examples will come for it. Where can I find them? I'm not so familiar with ffmpeg that I can put that together myself. :P

#161 did it for me. ;)
