Expose map.getImage

[alex3165]

Hello,

I would need to know if an image has already been added or not, would it be possible to expose a map.getImage function? I can see that addImage is already "protected":

  if (this.imageManager.getImage(id)) {
    return this.fire('error', {error: new Error('An image with this name already exists.')});
  }

But I would like to avoid the error message and prevent from calling map.addImage upfront by checking is the image is already there in my application.

mapbox-gl-js version: 0.42.2

I found some error. And 'try-catch' not helping.

try {
          this.map.addImage('arrow-head', image);
        } catch (e) {
          console.log('image with id "arrow-head" is already exists');
        }

Even if i use 'try-catch' i still get error.

vendor.bundle.js:44292 Error: An image with this name already exists.
    at t.addImage (vendor.bundle.js:44178) [angular]
    at e.addImage (vendor.bundle.js:44266) [angular]

Is the method "addImage" async?

@alex3165 we would gladly accept a PR implementing this method!

Note that #5775 implemented a Boolean hasImage() method but not a getImage() method.
