Get rid of warnings and remove cactus as an installation candidate

Describe the bug error when installing

To Reproduce Steps to reproduce the behavior:

cargo install --git https://github.com/curlpipe/ox

gives this error:

error: multiple packages with binaries found: cactus, ox. When installing a git repository, cargo will always search the entire repo for any Cargo.toml.
Please specify a package, e.g. `cargo install --git https://github.com/curlpipe/ox cactus`

and

cargo install --git https://github.com/curlpipe/ox cactus

gives:

Updating git repository `https://github.com/curlpipe/ox`
error: current package believes it's in a workspace when it's not:
current:   /home/kira/.cargo/git/checkouts/ox-4001c41b4fbbd7bf/344262a/kaolinite/examples/cactus/Cargo.toml
workspace: /home/kira/.cargo/git/checkouts/ox-4001c41b4fbbd7bf/344262a/Cargo.toml

this may be fixable by adding `kaolinite/examples/cactus` to the `workspace.members` array of the manifest located at: /home/kira/.cargo/git/checkouts/ox-4001c41b4fbbd7bf/344262a/Cargo.toml
Alternatively, to keep it out of the workspace, add the package to the `workspace.exclude` array, or add an empty `[workspace]` table to the package's manifest

Expected behavior A clear and concise description of what you expected to happen.

Does cargo install --git https://github.com/curlpipe/ox ox work?

yes but with these warnings:

Ah yeah, that... I recently changed around how ox was structured and it seems there are some teething problems

For now, I'll update the readme while I figure out how to dismiss all these warnings and errors

Got rid of the warnings in 0.5.3
