* fix(types): add notes to some buffer methods
* fix(types): remove since jsdoc comments from buffer
* chore(types): fix bundle script and build types
* fix(types): update bundle script
This really shouldn't do anything differently, but it no longer hangs whenever I bundle types. Not sure if anyone else has this problem but, ehhhh...
* fix(types): remove unused types in buffer
* feat(types): add assert module types
* feat(types): add events module types
* feat(types): add os module types
