+cargo-dist release archives are currently configured with the `full` feature

+Useful local release/package sanity checks:

+cargo fmt --check
+cargo test -p irtt-cli
+cargo clippy --workspace --all-targets -- -D warnings
+cargo build -p irtt-cli --release
+cargo build -p irtt-cli --no-default-features --release
