		Takes the dependencies computed using `getDependsInFolder` or `getDependentFiles` and a list of source files and produces a list of potentially affected files.

		const { getDependsInFolder, affectedFiles } = require('spec-change')
		const deps = getDependsInFolder(directory)
		const changedFiles = ['utils/sub/misc.js']
		const affected = affectedFiles(deps, changedFiles)
