Improve estimated matching with COCM update

[laurenluz]

We are using COCM to calculate the matching funds for rounds now in QF, so we should build a new way to calculate the estimated matching using that algorithm.

The COCM algo is here: https://github.com/Giveth/COCM_QF_Algorithm

In order to not bogg down our backend, I am curious to know what it would take to use this algorithm to calculate the matching funds... but we could run the code for example one per hour, or once per half hour.

@CarlosQ96 can you investiagte and report back what you think?

if you have any questions about the algo, @koday1 could offer some insights.
