I added the feature to output the data as numpy binary file. Although previously only text format was available, it was inconvenient due to the large file size.

• When you check the option of `Add a link to download data as text file`, the link of binary file will appear on the page. The option is valid for TimeSeries, WhitenedTimeSeries, AverageASD and  Spectrum. I attach the example.
• I upload the sample jupyter notebook to demonstrate how to read numpy binary file at JGWdoc.
• By using the numpy binary file, the file size was reduced 149MB --> 27MB for TimeSeries and 9MB --> 1.7MB for AverageASD, and also you can read the data quickly.
