CLI ignores nonexistent path

Running typeshare ./path/that/does/not/exist --lang=typescript --output-file=my_typescript_definitions.ts does not seem to throw an error

Hello, and thank you for reporting this! I'll be looking into this!

At the moment, we are discarding errors that result from converting the CLI-provided paths to walkable iterators. I'll bring this up with the team to discuss if there's a better way to handle these errors.
