Delete modules in a folder from require.cache unless the folder is unchanged since last call.
This is used by jscodeshift-choose-parser
to ensure that it always uses the current version of babel installed
in a project.
const invalidateRequireCache = require('invalidate-require-cache')
invalidateRequireCache('path/to/directory')
// now everything inside that directory has been deleted from require.cache
// (unless it is unchanged since the last call)
// and will be reloaded if you require it again.
