Every submodule under the 'crypto' directory was exported-imported even if a handful of functions where actually needed. We now only export entire modules behind default exports if it makes sense for readability and if the different submodules would be imported together anyway (e.g. `cipherMode` exports are all needed by the SEIPD class). We've also dropped exports that are not used outside of the crypto modules, e.g. pkcs5 helpers.
