feat: Add an export to call prepared statements

[thelindat]

Mostly intended for bulk queries to reduce overhead from calling multiple function references, as well as serve as a far better and safer alternative to hideous case and join queries utilised in ESX Status and ESX Legacy.

Needs testing and improvements. Adding another argument to state the number of queries expected to run would also be beneficial as we can use that to clean up some of the results and control the data being sent back. If we expect to run a single SELECT query, so we can either return results[0] or results[0][0] depending on the number of columns returned to reduce memory use; essentially giving us the benefits of both the single and scalar functions.

Status save function

function SaveData()
	local parameters = {}
	for _, xPlayer in pairs(ESX.GetExtendedPlayers()) do
		local status = ESX.Players[xPlayer.source]
		if status and next(status) then
			parameters[#parameters+1] = {json.encode(status), xPlayer.identifier}
		end
	end
	if #parameters > 0 then
		exports.oxmysql:prepared('UPDATE users SET status = ? WHERE identifier = ?', parameters)
	end
end

ESX (Ox) save function

Core.SavePlayers = function(cb)
	local xPlayers = ESX.GetExtendedPlayers()
	local count = #xPlayers
	if count > 0 then
		local parameters = {}
		local time = os.nanotime()
		for _, xPlayer in pairs(xPlayers) do
			parameters[#parameters+1] = {
				json.encode(xPlayer.getAccounts(true)),
				xPlayer.job.name,
				xPlayer.job.grade,
				xPlayer.group,
				json.encode(xPlayer.getCoords()),
				json.encode(xPlayer.getInventory(true)),
				xPlayer.identifier
			}
		end
		exports.oxmysql:prepared("UPDATE `users` SET `accounts` = ?, `job` = ?, `job_grade` = ?, `group` = ?, `position` = ?, `inventory` = ? WHERE `identifier` = ?", parameters,
		function(results)
			if results then
				if type(cb) == 'function' then cb() else print(('[^2INFO^7] Saved %s %s over %s ms'):format(count, count > 1 and 'players' or 'player', (os.nanotime() - time) / 1000000)) end
			end
		end)
	end
end
