Divide BIFI Maxi rewards between blockchains equally.

I propose that the APYs are the same between all blockchains, and that they are distributed once a week. If a blockchain performs better, it would not only be those who are on the considered blockchain who benefit from it, but all those who are in a BIFI Maxi pool. This would avoid having to use bridges every time we look for the best BIFI Maxi APYs
