TITLE - Replace

Status

• Ready
• Development
• Hold

Description

The main crate uses 0.12 already, and this removes the duplicated implementation of target-lexicon. No source changes seem to be needed

Checklist

• Ran cargo fmt, cargo clippy --all-targets, cargo build --release and cargo test and fixed any generated errors!
• Removed unnecessary commented out code
• Used specific traces (if you trace actions please specify the cause i.e. the player)

Note: if you locally don't get any errors, but GitHub Actions fails (especially at clippy) you might want to check your rust toolchain version. You can then feel free to fix these warnings/errors in your PR.
