is_finite() within arma::hist() under Armadillo 15.0.2-1 causing warning deprecation

Hi @conradsnicta,

Just a heads up, there is still a use of is_finite() within arma::hist() under Armadillo 15.0.2-1 that's biting a few R packages:

https://gitlab.com/conradsnicta/armadillo-code/-/blob/bb8bdf345810f5f4c02e2cce849411b17518346e/include/armadillo_bits/glue_hist_meat.hpp#L112
