interpolate

A participant in our USArray Data Processing short course this week discovered that SAC will happily "interpolate" to a larger DELTA value (fewer samples), and apparently does so without anti-alias filtering.
Would you consider building in an error message if the DELTA given to "interpolate" exceeds the DELTA in the SAC files in memory?

    Good point. This issue as come up a couple of times in various sac-help
    threads, but neither is there a warning message when running the program
    nor in the documentation. Should be both places. We will do it in
    v101.5.
