[PX] ADX and DI v4

Hey guys,

I recently used the "ADX and DI" indicator in a variety of my own scripts. Because I keep on developing version 4 scripts and the "ADX and DI" indicator is developed in one of the previous PineScript versions, I had to update the old script every time I wanted to use it. I decided to publish the updated version and also changed a few things:

- ADX color is now orange
- Instead of plotting the DI+ and DI- lines, it's filling the space between the two (can be changed in the "style"-section)

Maybe some of you find it useful. If so, leave a like or follow :)

Happy trading,
paaax

P.S: The original indicator was developed by the user @MasaNakamura. Thanks for your great work!
