Add "new historical low" and "historical low" filters on /bundles page

[enchained]

I noticed that you've started tracking the bundle price history and it's really great, thanks!

Maybe now with that data it will be possible to implement new filters for the https://steamdb.info/bundles/? It already has "Show only bundles currently on sale" filter, but the complimentary "show only blue/green", similar to the /sales filters, could be extremely useful.
