[Feature request] provide more context for lastResortScript

[Rush]

Thanks for building this plugin! My users suffer from intermittent issues loading the async chunks so this will provide some relief.

I just set the lastResetScript to the following.

      lastResortScript: `(${(function(chunkId: string) {
        alert('Sorry, we couldn\'t load required script \'' + chunkId + '\'. Please contact support if the issue persists');
      }).toString()})(chunkId);`,

But it seems only chunkId is available in the context. Some of my chunks are actually not critical if they fail, in such case I would like to provide an alternative message:

      lastResortScript: `(${(function(chunkId: string, chunkName: string) {
        if (chunkName.startsWith('opt-')) {
          // provide some softer error than alert
        } else
          alert('Sorry, we couldn\'t load required script \'' + chunkId + '\'. Please contact support if the issue persists');
        }
      }).toString()})(chunkId, chunkName);`,

Thanks again!

Hello,

i have the same issue, and there is actually more data you can access:

realSrc will give you the path of the chunks like : js/chunks/home.js
error will give you the string of the error as printed in the console.warn
