build!: remove implicit features

This will be the default with the upcoming Edition 2024 as it caused confusion. See https://doc.rust-lang.org/nightly/edition-guide/rust-2024/cargo-remove-implicit-features.html

BREAKING CHANGE: Optional dependencies are no longer features. They were never intended to be used directly.
