subscriber: prepare to release 0.2.0 stable

0.2.0 (February 4, 2020)

Breaking Changes:

- **fmt**: Renamed `Context` to `FmtContext` (#420, #425)
- **fmt**: Renamed `Builder` to `SubscriberBuilder` (#420)
- **filter**: Removed `Filter`. Use `EnvFilter` instead (#434)

Added:

- **registry**: `Registry`, a reusable span store that `Layer`s can use
  a high-performance, in-memory store. (#420, #425, #432, #433, #435)
- **registry**: Added `LookupSpan` trait, implemented by `Subscriber`s
  to expose stored span data to `Layer`s (#420)
- **fmt**: Added `fmt::Layer`, to allow composing log formatting with
  other `Layer`s (#420)
- **fmt**: Added support for JSON field and event formatting (#377,
  #415)
- **filter**: Documentation for filtering directives (#554)

Changed:

- **fmt**: Renamed `Context` to `FmtContext` (#420, #425) (BREAKING)
- **fmt**: Renamed `Builder` to `SubscriberBuilder` (#420) (BREAKING)
- **fmt**: Reimplemented `fmt::Subscriber` in terms of the `Registry`
  and `Layer`s (#420)

Removed:

- **filter**: Removed `Filter`. Use `EnvFilter` instead (#434) (BREAKING)

Fixed:

- **fmt**: Fixed memory leaks in the slab used to store per-span data
  (3c35048)
- **fmt**: `fmt::SubscriberBuilder::init` not setting up `log`
  compatibility (#489)
- **fmt**: Spans closed by a child span closing not also closing _their_
  parents (#514)
- **Layer**: Fixed `Layered` subscribers failing to downcast to their
  own type (#549)
- **Layer**: Fixed `Layer::downcast_ref` returning invalid references
  (#454)
