Axis 'title' position alignment

[romanimm]

Currently there is no way to define the alignment for the xAxis / yAxis title.
For example if I want the xAxis title on the left, I have to position the title with offsets: options: { xAxis: { title: { text: 'Jahre', offsetX: -840, offsetY: -15 }}. This works fine if the chart has a fixed size, but breaks if the chart is responsive.

Example:

      const el = document.getElementById('chart-area');
      const data = {
        categories: [1,2,3,4,5,6,7,8,9,10],
        series: [
          {
            name: 'Aktien',
            data: [5000, 6000, 6200, 7000, 8000, 8900, 10000,11000,12000,14000,15000],
          },
          {
            name: 'Wachstum',
            data: [5030, 6050, 6260, 7070, 8030, 8920, 10500,11060,12700,14800,15300],
          },
          {
            name: 'Asugewogen',
            data: [5100, 6300, 6400, 7300, 8020, 8900, 15000,11200,12500,14600,15500],
          },
        ],
      };
      const options = {
        chart: {width: 'auto', height: 400,}, 
        legend: {visible: false}, 
   		theme: {
             series: {barWidth: 40, colors: ['red', 'blue', 'yellow',] },
            xAxis: {color: 'transparent'},
        	yAxis: {color: 'transparent'},  
            plot: {
            	vertical: {
                lineColor: 'transparent', lineWidth: 0,
                },
            },
        },
           yAxis: {
              
        label: { formatter: (value, infos) => {return value === '0'?  '': parseInt(value)}},
    },
          xAxis: { title:{text: 'Jahre', offsetX: -840, offsetY: -15}, pointOnColumn: true },
        series: { stack: { type: 'normal' } },
           responsive: {
    animation: { duration: 300 },
    rules: [
      {
        condition: ({ width: w }) => {
          return w <= 800;
        },
        options: {
          xAxis: {
            tick: { interval: 2 },
            label: { interval: 2 }
          },
        }
      },],
        },
      };

      const chart = toastui.Chart.areaChart({ el, data, options });
// "Jahre" is at the wrong position if el is not 900px wide.
    ```
    
Well, one could define responsive conditions for every width and set the correct offset for each of it, but the nicer API would certainly be if the title becomes an alignment option.
