Bug fix in the new implementations of binomial crossover types released in 0.19.4

PR 1088

Massive improvement to the performance of simulations using genetic maps with a large number of PoissonInterval classes.

**These changes mean that simulations with many regions will give different results for the same random number seed.**

1087 (see issue 1082)

This release also include several back-end changes getting ready to use demes models directly.
See the detailed change log in the manual.

Deprecations

* The low-level Python API for defining demographic events
is now deprecated and will raise warnings.
No action has to be taken yet.
There is no replacement API to migrate to.
