Add period configuration option to anomaly_detect_ts

[triciascully]

I've been manually running the code and setting the period to period = 96 because the data I'm working with is at a 15min interval - can you build in an option for configuration of the period when calling the function, since people might be working with data that's every 10min, 15min, 30min, 2hrs, etc.?
