--no-default-features on strict-encoding not taking effect

[6293]

Here is the output of cargo build -p strict_encoding -v --no-default-features:

rustc --crate-name strict_encoding --edition=2021 rust/src/lib.rs --error-format=json --json=diagnostic-rendered-ansi,artifacts,future-incompat --diagnostic-width=181 --crate-type lib --emit=dep-info,metadata,link -C embed-bitcode=no -C split-debuginfo=unpacked -C debuginfo=2 --cfg 'feature="default"' --cfg 'feature="derive"' --cfg 'feature="strict_encoding_derive"' -C metadata=e188277cae2a4737 -C extra-filename=-e188277cae2a4737 --out-dir /Users/yudaikiyofuji/IdeaProjects/strict-encoding/target/debug/deps -C incremental=/Users/yudaikiyofuji/IdeaProjects/strict-encoding/target/debug/incremental -L dependency=/Users/yudaikiyofuji/IdeaProjects/strict-encoding/target/debug/deps --extern amplify=/Users/yudaikiyofuji/IdeaProjects/strict-encoding/target/debug/deps/libamplify-be50d4e6df4ec592.rmeta --extern strict_encoding_derive=/Users/yudaikiyofuji/IdeaProjects/strict-encoding/target/debug/deps/libstrict_encoding_derive-627116894db1dd46.dylib

You can see the feature default is unexpectedly activated. This is likely because we have a dev-dependency strict_encoding_test which is circularly dependent on strict-encoding.
