The transitive dependency on itoa 0.4 does not compiles with stablerust. Bump inferno to 0.12.1 to fix this.```❯ cargo check --examples    Checking serde v1.0.157    Checking tokio v1.43.0    Checking itoa v0.4.0    Checking tracing-macros v0.1.0 (/Users/joshka/local/tracing/tracing-macros)error[E0554]: `#![feature]` may not be used on the stable release channel  --> /Users/joshka/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/itoa-0.4.0/src/lib.rs:13:31   |13 | #![cfg_attr(feature = "i128", feature(i128_type, i128))]   |                               ^^^^^^^^^^^^^^^^^^^^^^^^   |   = help: the feature `i128_type` has been stable since `1.26.0` and no longer requires an attribute to enable``````❯ cargo tree -i itoa@0.4.0itoa v0.4.0└── num-format v0.4.0    └── inferno v0.11.6        [dev-dependencies]        └── tracing-examples v0.0.0 (/Users/joshka/local/tracing/examples)```

This example demonstrates how to use the `tracing-subscriber` crate's`EnvFilter` type to filter log messages based on their metadata. Theexample provides a text area where users can input an environment filterstring, and displays the log messages that would be captured by thatfilter.
