Hi Martin,

It's me again ^^'

As title, could you allow one to simulate sequences with non-uniform recombination rates? And maybe allow one to use the rates from available data, such as HapMap, like the RateMap.read_hapmap() function in msprime (https://tskit.dev/msprime/docs/stable/api.html#msprime.RateMaphttps://tskit.dev/msprime/docs/stable/api.html#msprime.RateMap)?

Thank you again.
