Feature request: ZigZag indicator

[jannostern]

Hi @bennycode,

Thank you for the awesome work on this library so far!
Have you also considered implementing a ZigZag indicator?

Something similar that TradingView has would be great.

@jannostern an implementation is on its way (#804). Can you share some testing values with me so I can validate the implementation?

Apologies @bennycode I do have Github notifications turned off, so did not notice your message until just now, as I was browsing your repository for most recent updates.

Give me a couple of days to play around with your implementation and come back with some initial thoughts.
