- Accept samples-like for `initial_states` (use `dimod.Initialized` ABC)

Fixes
---

- Updated Windows tests to work with latest AppVeyor setup
- Stopped using hierarchical requirements include

Fixes

- Docs updates
- Correct setup requirements
- Test with dimod 0.9.x by default

Changes
-------
* Drop support for python 2.7 and 3.4

Fixes
-----
* Loosened NumPy version requirements

Fixes
---

- Publish Python 3.8 wheels for Linux/macOS/Windows
- Publish binary wheels for macOS 10.9+ (previously 10.13+)

New Features
---

- Exposed `default_beta_range` estimator for a custom BQM

Fixes
---

- Not specifying `initial_states` was raising a deprecation warning. It
shouldn't, so now it doesn't.

New Features
------------

* `SampleSet` accepted for `initial_states` value

* `initial_states` are truncated or expanded to match the
number of reads, and the expansion algorithm is controlled
with a new parameter, `initial_states_generator`

* Undefined `num_reads` inferred from `initial_states`

Fixes
-----

* For `initial_states` given in the 2-tuple format, infer the
vartype from the BQM

* Avoid GIL locks when interrupt function not defined

Deprecations
------------

* The 2-tuple format (NumPy array + variable labels) for
`initial_states` in favor of `SampleSet`

* `sweeps` parameter in favor of `num_sweeps`

Breaking changes
----------------

* New default value for `num_reads`: now matches `initial_states`
length, or defaults to 1
