Add cargoBench

[asymmetric]

Allows running cargo benchmarks easily via crane.

Motivation

Noticed this was missing in a project I'm working on using crane.

Creating as a draft to gauge interest before sinking more time into this :)

Checklist

• added tests to verify new behavior
• added an example template or updated an existing one
• updated docs/API.md (or general documentation) with changes
• updated CHANGELOG.md
