zoomIn basic work #50

with tihs options

let options = {
        renderLegend: false, usePanning: false,
        axis: { y: { range: [0, 50] } },
        zoomEvents: { mouse: {
          zoom: { isActive: true, orientation: "horizontal" },
          pan: { isActive: false },
        }},
        eventsCallbacks: {
          zoomOut: function(centers, ranges) {
            console.log('zoomOut', centers, ranges);
          }
        }
      }

zoomOut works, but not zoomIn

I get Chartwerk Core: skip brush end (no extent) index.js:1:71053 warning when I zoomIn
