> We no longer allow seeking in IndexOutput, so there is no need to use RandomAccessFile.
We can change this with a < 1 KiB patch.
> Further improvements would be to merge this with OutputStreamIndexOutput, so we get many
simplifications.
> There is also no reason anymore to separate DataOutput from IndexOutput. The only additional
thing is IndexOutput#getFilePointer(), which is handled by  an internal counter (does not
use getFilePointer of the underlying RAF) and checksums.
