core: prepare to release 0.1.20 (tokio-rs#1554)

# 0.1.20 (September 12, 2021)

This release adds support for `f64` as one of the `tracing-core`
primitive field values, allowing floating-point values to be recorded as
typed values rather than with `fmt::Debug`. Additionally, it adds
`NoSubscriber`, a `Subscriber` implementation that does nothing.
### Added

- **subscriber**: `NoSubscriber`, a no-op `Subscriber` implementation
  ([tokio-rs#1549])
- **field**: Added `Visit::record_f64` and support for recording
  floating-point values ([tokio-rs#1507])

Thanks to new contributors @jsgf and @maxburke for contributing to this
release!
