Move certain settings stored in DB to JSON string saved in LONGTEXT

This would allow for not needing stuff like this:

let results = await sqlPool.query(`
  SELECT botID, channelID, SUB, SUB_T2, SUB_T3, SUB_PRIME, RESUB, RESUB_T2, RESUB_T3, RESUB_PRIME, SUBGIFT, ANONSUBGIFT, SUBMYSTERGIFT, GIFTPAIDUPGRADE, ANONGIFTPAIDUPGRADE, REWARDGIFT, RAID, RITUAL
  FROM notifications
  WHERE botID = ?;
`, botID)
// ...

but instead something like this:

let results = await sqlPool.query(`
  SELECT botID, channelID, data
  FROM notifications
  WHERE botID = ?;
`, botID)
// ...
return results.map((line) => {line.data = JSON.parse(line.data)})

Obviously with try {} catch {} and other checks
