Feature Request: Add option to read from stdin output

[danielpza]

Adding the option to read/write to stdin/out would make it easier to use as an editor plugin

ts-import-types-cli < input.ts

Hey @danielpza,
I will certainly accept PRs but I'm otherwise not maintaining this package any more because the following packages give me what I need:

1. https://github.com/import-js/eslint-plugin-import
2. https://github.com/thorn0/organize-imports-cli

When I created this package I wasn't aware of the above.

Thanks.
