subscriber: prepare to release v0.3.10 (tokio-rs#2041)

# 0.3.10 (Apr 1, 2022)

This release adds several new features, including a `Filter`
implementation and new builder API for `EnvFilter`, support for using a
`Vec<L> where L: Layer` as a `Layer`, and a number of smaller API
improvements to make working with dynamic and reloadable layers easier.

### Added

- **registry**: Implement `Filter` for `EnvFilter`, allowing it to be
  used with per-layer filtering ([tokio-rs#1983])
- **registry**: `Filter::on_new_span`, `Filter::on_enter`,
  `Filter::on_exit`, `Filter::on_close` and `Filter::on_record`
  callbacks to allow `Filter`s to track span states internally ([tokio-rs#1973],
  [tokio-rs#2017], [tokio-rs#2031])
- **registry**: `Filtered::filter` and `Filtered::filter_mut` accessors
  ([tokio-rs#1959])
- **registry**: `Filtered::inner` and `Filtered::inner_mut` accessors to
  borrow the wrapped `Layer` ([tokio-rs#2034])
- **layer**: Implement `Layer` for `Vec<L: Layer>`, to allow composing
  together a dynamically sized list of `Layer`s ([tokio-rs#2027])
- **layer**: `Layer::boxed` method to make type-erasing `Layer`s easier
  ([tokio-rs#2026])
- **fmt**: `fmt::Layer::writer` and `fmt::Layer::writer_mut` accessors
  ([tokio-rs#2034])
- **fmt**: `fmt::Layer::set_ansi` method to allow changing the ANSI
  formatting configuration at runtime ([tokio-rs#2034])
- **env-filter**: `EnvFilter::builder` to configure a new `EnvFilter`
  prior to parsing it ([tokio-rs#2035])
- Several documentation fixes and improvements ([tokio-rs#1972], [tokio-rs#1971],
  [tokio-rs#2023], [tokio-rs#2023])

### Fixed

- **fmt**: `fmt::Layer`'s auto traits no longer depend on the
  `Subscriber` type parameter's auto traits ([tokio-rs#2025])
- **env-filter**: Fixed missing help text when the `ansi` feature is
  disabled ([tokio-rs#2029])
