As it is now, it is impossible to use the mode
"read 1 sample every N frame" with PIOlib.
It is heavily slow because KST makes a request
to read only one sample at a time.
It would be much faster to give to PIOlib a vector
of index.

Data source is now as efficient as piolib allows it to be.  kst_fastskip_branch contains a kstrvector which takes advantage of this, and will be merged soon.
