Extraction events

A nice addition to this package would be emitting events such as `progress` and `entry` so that implementers can see how far along they are with their decompression and to know what the currently decompressing or decompressed file is.

```
const zip = new Decompress()
.src(src)
.dest(dest)
.use(Decompress.zip())
.on('progress', pe => {
if (pe.lengthComputable) {
const percent = Math.round(pe.decompressed / pe.total * 100);
console.log(`${percent}% complete`);
}
})
.on('entry', entry => {
console.log(`Currently decompressing ${entry.fileName}.`);
})
.run();
```

The `progress` event data I modeled after the Web API standard: https://developer.mozilla.org/en-US/docs/Web/API/ProgressEvent and modified `loaded` to `decompressed`.

The `entry` event data I modeled after information found in the zip specification on wikipedia.

Start by reading the Decompress chain and the Decompress.zip() entry point named in the issue, then inspect how extraction currently reports work. Define the progress and entry event data from the Web API ProgressEvent and zip-specification references, and verify that consumers can observe decompression progress and the current file.
