profiling (don't merge!)

WITHOUT simplification/checking/computing tree sequence or other

• about 60% of time is spend in argrecorder.py
• most of this (46%) is in argrecorder.py:add_record and 3/4 of that in stuff that is not msprime (which takes up total of 10% of the 46% for argrecorder.py in the flame graph from command below) --- so mostly the logic in argrecorder.py:merge_records and buildin logic of OrderedDict.

you can re-run (from project root after first pip install vprof):

vprof -c cmp tests/test_recomb_collector.py
