Description
Why?
Some smime messages consists of a p7m attachment that encapsulate the mime structure and their display is suboptimal in the webmail
We wishes to offer essentials for nicer display in the wemails
IE when opening the mail a display similar to the one of thunderbird:
What
Offer a SMimeP7M/parse JMAP route that would allow parsing those messages and expose them as EmailBodyStructure
Note that we also need to handle download of such body parts.

},

]
}
Note that body parts blobId follow the following syntax: smimep7m_{nested-blobid}?{path-to-mimepart within smime message}
So smimep7m_123456?1_2_3 means take message 123456 and interpret it as smimep7m then take the first body part of the first multipart and then the second body of the second multipart and then the trird of the most inner multipart.
Nesting a p7m in a p7m is out of scope.
