Remove tskit from msprime
Separation of tskit from msprime. Msprime is now solely dedicated to simulating the coalescent, and all infrastucture for working with succinct tree sequences is now provided by tskit. To ensure compatability, msprime now imports code from tskit under the old names, which should ensure that all code continues to work without changes.
New features
