Add an implentation of the KMTNet detection algorithm

[Somayeh91]

We need to add an implentation of the KMTNet detection algorithm from https://ui.adsabs.harvard.edu/abs/2018AJ....155...76K/abstract

Atousa has uploded the code here: https://github.com/LSST-TVSSC/microlensing/blob/main/antares_filter/KMTNET_Algorithm.py
Rachel and I tested the detection algorithm on DP1 data. The algorithm seems to work fine. We are working on some filtering criteria to decrease the size of the sample we will fit with the detection algorithm.
