Fail on non-dev packages with executables that are only used within `bin/`

[matthewnitschke-wk]

Motivation

• Closes #106
• Closes #99

Changes

dependency_validator passes if there is a non-dev (dependencies:) dep, that contains executables, but is only referenced within the bin/ directory

Under the following conditions, the dependency should be downgraded to a dev_dependency, and dependency_validator exits with a non-zero exit code

[!IMPORTANT] Merging this PR has a chance to break existing implementations, we may want to do this as a major, depending on how best we want to support current implementations of dep validator
