continue #199: redesign the bundled file structure

According to @eoghanmurray's suggestion, we can support three
main scenarios:
1. record only
2. replay only
3. all in one

Since we have implemented the packer feature, which has a big
influence in bundle size, we provide another three bundles:
1. record and pack
2. replay and unpack
3. all in one with pack and unpack
