> We skip a great deal to avoid materializing data. Ironically, however, skipping is just as (perhaps more) expensive, as it allocates a temporary array of the size of the number of bytes we want to skip.
> This trivial patch implements {{skipBytes}} more efficiently, and simplifies {{FileUtils.skipBytesFully}}
