* removes unused filesize function * removes ioutil usage * updates ioutil.ReadAll to io.ReadAll * updates ioutil.TempFile to os.CreateTemp * updates ioutil.TempDir to os.MkdirTemp * updates ioutil.ReadAll to os.ReadAll * update ioutil.WriteFile to os.WriteFile * updates ioutil.Discard to io.Discard * updates ioutil.ReadDir to os.ReadDir where applicable * removes unused code in idk * creates type to use for context value keys * replaces assert.Nil with assert.NoError for error checks
