chore(MailParts) made it simpler/more understandable by removing `Embedded` type

- Now `MailParts` and `BodyParts` have two arrays each one for `inline_embeddings`
  and one for `attachments` instead of mixing them togetther.
- Now requires `Resource` instances instead of `Embedded` instances which wrap
  resource and add wether it's inline or attachment.
