fix: print_replay test generation & raw_to_tmcpr config state

- Fix SaveUnCodeAbleAsTest using wrong package name (1.8.9 vs v1_8)
- Fix test template using bytes.Buffer instead of bytes.NewReader
- Tests now fail when decode SUCCEEDS (bug is fixed)
- Add config state support to raw_to_tmcpr with -config flag
- Fix mca_to_tmcpr -world flag being ignored
