Dwave-system

Fixes

* Fix the default `time_limit` calculation in `LeapHybridCQMSampler`. See https://github.com/dwavesystems/dwave-system/issues/482.

Upgrade Notes

* Use `SciPy>=1.7.3`
* Use `dwave-samplers` rather than `dwave-greedy`
* Use `NumPy>=1.20.0`
* Use `dwave-preprocessing>=0.5.0`
* Use `dimod>=0.12.0`

New Features

* Respect low-level solver order on failover. See [479](https://github.com/dwavesystems/dwave-system/issues/479).

What's Changed
* Fix QPU failover by signaling solver failover condition (on resolve). See https://github.com/dwavesystems/dwave-system/pull/465
* Exact-solve for ground state in `MockDWaveSampler` on small problems. See https://github.com/dwavesystems/dwave-system/pull/476
* Add `dwave.systems.temperature` submodule with `effective_field`, `maximum_pseudolikelihood_temperature`, `freezeout_effective_temperature`, `fast_effective_temperature` functions. See https://github.com/dwavesystems/dwave-system/pull/436

New Features

* Remove the upper bound on `dwave-preprocessing`'s version

New Features
* Add support for Zephyr topology and new solver property `per_group_coupling_range` to `DWaveCliqueSampler`.
* Introduce `dwave.embedding.zephyr` module.

Fixes
* Fix deprecation warning in `LeapHybridSampler`.
