[Kst] netCDF datasource in the works...

Kst really needs random access data.  For ascii, one has the same problem, so 
we pre-parse to make a lookup table of row start bytes in order to do this.

If frameCount is expensive, but everything else is fine, you could consider 
having frameCount return a large number until it knows better - read from end 
will break but reading from pre-defined ranges should work fine.
