You can now run `./readbenchfs --mount_point dir --vectored` and then
`dd if=dir/test of=/dev/null iflag=direct bs=1M status=progress` to test
vectored read speed.
My results with GOMAXPROCS=1:
- Before vectored read patch: 390 MB/s read
- Non-vectored read after vectored read patch: 830 MB/s read
- Vectored read: 1200 MB/s read
