Smimesign Versions Save

Release notes:

• Three dependencies have now been moved into github.com/smimesign directly:
  • github.com/smimesign/certstore
  • github.com/smimesign/fakeca
  • github.com/smimesign/ietf-cms

There are no other changes. The minor version bump delineates the presence of the new packages inside smimesign itself.

• Add reading from message file capacity to signing command.
