Dwave-hybrid

Fixes
---
- Support all structured samplers in `SubproblemCliqueEmbedder` (271)

Fixes
---
- Fixed `State.from_sample` to accept `SampleSet`. Fixed `KerberosSampler` to accept `SampleSet` for initial state (268)

Upgrade Notes
---
- Drop Python 3.6 support (269)

New Features
---

- Support `dimod<0.13.0` (266)

Fixes
---

- Docs refresh (262)

New Features

- Add `hybrid.Log`, a block to log user-define state metrics to a JSON file, python logger, or in-memory queue or list. See [\257](https://github.com/dwavesystems/dwave-hybrid/pull/257).

- Add convenience JSON encoders for commonly used NumPy (`hybrid.utils.NumpyEncoder`) and Ocean types (`hybrid.utils.OceanEncoder`). See [\257](https://github.com/dwavesystems/dwave-hybrid/pull/257).

Fixes

- Clarify docs, [\142](https://github.com/dwavesystems/dwave-hybrid/issues/142).

Upgrade

- Drop dimod 0.8.x support. Oldest supported dimod version is now 0.9.6. See [\259](https://github.com/dwavesystems/dwave-hybrid/pull/259).

New Features
---
- `make_origin_embeddings` problem decomposing utility that creates optimal embeddings for a lattice.
Embeddings are compatible with the topology and shape of D-Wave QPU samplers (https://github.com/dwavesystems/dwave-hybrid/pull/252).
- `SublatticeDecomposer` that produces lattice-structured subproblems (https://github.com/dwavesystems/dwave-hybrid/pull/252).

Fixes
---
- `SteepestDescentProblemSampler` now actually uses `greedy.SteepestDescentSolver` (https://github.com/dwavesystems/dwave-hybrid/pull/250).

Fixes
---
- Support dimod 0.10 (https://github.com/dwavesystems/dwave-hybrid/pull/248)
