…t for cgroup v2 update calc_mem.py script used to obtain within-container memory limit for cgroup v2, obtaining memory limit from new read-only file, falling back to psutil-based approach. Additionally, allow calc_mem.py to return memory values in kb or b. Also update CPU limit for cgroup v2 in calc_mem.py and util.misc; add psutil to conda requirements
expand unit tests of util.misc.available_cpu_count() to include tests where cgroup v2 is used, where cgroup v1 is used, where limits are imposed (or not) on either, or where multiprocessing.cpu_count() is used as the fallback in the event a hex bitmask cannot be found in the usual fallback of /proc/self/status
