Move mouse over the channel
**should be used inside async with `await`** operator.
@param {Object} [atPoint] - Point where will be called wheel action
@param {number} [atPoint.x=0.5] - relative X coordinate
@param {number} [atPoint.y=0.5] - relative Y coordinate
@returns {Promise<void>}

@example
await AtTimeSeries.moveMouseOverChannel({ x: .01 });
