feat(cmd): `. export`

[sudojunior]

Intention to add a command to export a message configuration for use on a website like discohook. Exporting to that specific site requires encoding a payload from an array of messages and an array of targets.

{
  "message": [
  ],
  "targets": [
    { "url": "https://discord.com/api/v10/webhook/123/uJp30PUtedu9M_DAIZQwhtENIZGaJV7ffTPTreEmEXEHR7Ys4TprLQ-_" }
  ]
}

Buffer.from(JSON.stringify({ messages, targets: [`https://discord.com/api/webhooks/v10/${webhook.id}/${webhook.token}`] })); // 'encode'
JSON.parse(Buffer.from("", "base64").toString()); // 'decode'

• Options to include webhook is another option...
• Prerequisite of requiring a message cache may be needed if templating uses prior message data (i.e. message or channel id)

  author, id, channel_id, pinned, timestamp, application_id are all returned, which the current run sequence may not be aware of prior to running. If back to top or a table of contents is intended, this would break the templating.
