 Returns a `Promise` which resolves to the original readable stream argument, but with an added `fileType` property, which is an object like the one returned from `FileType.fromFile()`.
 
-Very handy to put in between a stream, but it comes with a price. Internally `stream()` builds up a buffer of `sampleSize` bytes, used as a sample, to determine the file type. The sample size impacts the file detection resolution. A smaller sample size will result in lower probability of the best file type detection.
