[Feature Request] Add interpolated recall-precision plot function about ranx

[AmenRa]

Hi, thanks for the very detailed suggestion/request!
I think this would be a nice addition to the library!
I will take a look to the linked documents in the coming days.

I found a really nice lecture on youtube, which explains the recall-precision plot really nice. It can be found here:

I also found out, that the official trec_eval program (https://github.com/usnistgov/trec_eval) returns the values for creating this plot. My workaround is actually, that i create runs using ranx, export the runs to a .trec-file and use the official trec_eval program

Hi, sorry for the delay.
I finally have a working implementation for computing the graph!
I still have to figure out a couple of usability things.
You can expect to be able to compute the Precision-Recall graph with ranx soon.

Hi, I added the Interpolated Precision-Recall Curve in v0.3.8.
I tested my implementation against trec_eval for correctness.
You can find a usage example here.

Please, let me know if you have any comment / suggestion.
