> S3AInputStream.skip() to use lazy seek

> the default skip() does a read and discard of all bytes, no matter how far 
> ahead the skip is. This is very inefficient if the skip() is being done on 
> S3A random IO, though exactly what to do when in sequential mode.
> Proposed: 
> * add an optimized version of S3AInputStream.skip() which does a lazy seek, 
> which itself will decided when to skip() vs issue a new GET.
> * add some more instrumentation to measure how often this gets used
