One option is to run cargo locate-project with --message-format plain to avoid parsing json.
$ pwd
/home/ubuntu/git/kani/tests/cargo-kani/config/src
$ cargo locate-project
{"root":"/home/ubuntu/git/kani/tests/cargo-kani/config/Cargo.toml"}
$ cargo locate-project --message-format plain
/home/ubuntu/git/kani/tests/cargo-kani/config/Cargo.toml

Done, though while debugging why everything suddenly failed (there is a newline in the bytes, oh), I realized I should update a bit of the error handling here too.

Description of changes:
While bumbling around trying to find the name of "this crate" I basically implemented this, so I've cleaned this up to submit separately from anything else.
Resolved issues:
Resolves #717
Call-outs:
Contains a few extra cleanups and comments unrelated to headline feature.
Testing:
How is this change tested? existing suite. Notably not really feasible to add to our cargo-kani test suite since the way all those invocations work specifies the working directory. But it does work now to e.g. call
cargo-kanifromsrcIs this a refactor change? basically yes
