Xorjson

Fixed

- Fix inaccuracy in deserializing some `float` values, e.g.,

Changed

- `orjson.dumps()` now serializes `datetime.datetime` objects without a
`tzinfo` rather than raising `JSONEncodeError`.

Changed

- `orjson.loads()` uses SSE2 to validate `bytes` input.

Changed

- Support Python 3.5.

Changed

- Publish Windows wheel.

Added

- `orjson.dumps()` accepts a `default` callable to serialize arbitrary
types.
- `orjson.dumps()` accepts `datetime.datetime`, `datetime.date`,
and `datetime.time`. Each is serialized to an RFC 3339 string.
- `orjson.dumps(..., option=orjson.OPT_NAIVE_UTC)` allows serializing
`datetime.datetime` objects that do not have a timezone set as UTC.
- `orjson.dumps(..., option=orjson.OPT_STRICT_INTEGER)` available to
raise an error on integer values outside the 53-bit range of all JSON
implementations.

Changed

- `orjson.dumps()` no longer accepts `bytes`.
