bem_random_stream Module

逐次に引く PCG64 の乱数列（Fortran 組み込み random_number の置き換え）。

seed_random_stream で seed を決めると、各 OpenMP thread は (seed, thread 番号) から作った自分の PCG64 stream を 初回の draw で開く。同じ seed・同じ thread で引けば同じ列になる。バッチ粒子の生成と粒子追跡は bem_counter_rng の counter-based 乱数を使い、この列は単体の sampling API と test だけが使う。
