v0.17.0

• Changed. Requires rasuvaeff/property-testing-core ^1.0 — the
  engine's stability release, whose surface is that of 0.12.0 — in place of
  ^0.10 || ^0.11; the dev requirement on rasuvaeff/property-testing-testo
  is ^1.0 likewise. Nothing in the generators or the runner changes: the
  release is the constraint, so a project on the 1.0 family can install this
  package beside it. rasuvaeff/openapi-contract stays at ^0.13; this
  package's own 1.0 waits for the contract's.
