Add exemplary hexyl plugin

* Make the default macOS theme depend on Dark Mode

We frequently get complaints from macOS users that bat does not work on
their default macOS terminal background, which is white.

Pay the price of slightly increased startup time to get a better default
on macOS. To avoid the slightly increased startup time, simply specify a
theme explicitly via `--theme`, `BAT_THEME`, or `~/.config/bat`.

Note that if there is an error when we check if Dark Mode is enabled, we
behave the same as on Windows and Linux; assume that the terminal
background is dark. This harmonizes behavior across platforms, and makes
bat behave the same as before, when Dark Mode was always assumed to be
enabled.

* src/assets.rs: Fix typo

* Update CHANGELOG.md

+- Make the default macOS theme depend on Dark Mode. See #2197, #1746 (@Enselic)

+## Themes

+
+
+# v0.21.0
+
+## Features
+
+- Correctly render tab stops in `--show-all`, see #2038 (@Synthetica9)
+- Add a `--style=default` option and make it the default. It is less verbose than `full`, see #2061 (@IsaacHorvath)
+- Enable BusyBox `less` as pager, see #2162 (@nfisher1226)
+- File extensions are now matched case-insensitively. See #1854, #2181 (@Enselic)
+
+## Bugfixes
+
+- Bump `regex` dependency from 1.5.4 to 1.5.5 to fix [CVE-2022-24713](https://blog.rust-lang.org/2022/03/08/cve-2022-24713.html), see #2145, #2139 (@Enselic)
+- `bat` no longer crashes when encountering files that references missing syntaxes. See #915, #2181 (@Enselic)
+
+## Performance
+
+- Skip syntax highlighting on long lines (> 16384 chars) to help improve performance. See #2165 (@keith-hall)
+- Vastly improve startup time by lazy-loading syntaxes via syntect 5.0.0. This makes bat display small files ~75% faster than before. See #951, #2181 (@Enselic)
+
+## Other
+
+- Include info about custom assets in `--diagnostics` if used. See #2107, #2144 (@Enselic)
+
+## Syntaxes
+
+- Mapped clang-format config file (.clang-format) to YAML syntax (@TruncatedDinosour)
+- log syntax: improved handling of escape characters in double quoted strings. See #2123 (@keith-hall)
+- Associate `/var/spool/mail/*` and `/var/mail/*` with the `Email` syntax. See #2156 (@cyqsimon)
+- Added cmd-help syntax to scope --help messages. See #2148 (@victor-gp)
+- Slightly adjust Zig syntax. See #2136 (@Enselic)
+- Associate `.inf` files with the `INI` syntax. See #2190 (@Enselic)
+
+## `bat` as a library
+
+- Allow configuration of `show_nonprintable` with `PrettyPrinter`, see #2142
+- The binary format of syntaxes.bin has been changed due to syntaxes now being lazy-loaded via syntect 5.0.0. See #2181 (@Enselic)
+- Mark `bat::error::Error` enum as `#[non_exhaustive]` to allow adding new variants without future semver breakage. See #2181 (@Enselic)
+- Change `Error::SyntectError(syntect::LoadingError)` to `Error::SyntectError(syntect::Error)`. See #2181 (@Enselic)

+#### Highlighting `--help` messages
+
+You can use `bat` to colorize help text: `$ cp --help | bat -plhelp`
+
+You can also use a wrapper around this:
+
+```bash
+# in your .bashrc/.zshrc/*rc
+alias bathelp='bat --plain --language=help'
+help() {

+
+Then you can do `$ help cp` or `$ help git commit`.
