ability to download plain attachments

[tomholub]

part of #275, after #193

You may for now ignore if the attachment is encrypted or plain. Simply, please download and save to user's device the attachment as it comes from the email provider (meaning, if it happens to be encrypted, then for now it will download the attachment without decrypting it)

Core's method parseDecryptMsg(encrypted: Data, keys: [PrvKeyInfo], msgPwd: String?, isEmail: Bool) parsed message with attachment with empty attachment block. Instead of it parses attachment as a text with following parameters "{"text":"[image: Screenshot 2021-05-18 at 21.50.28.png]","replyType":"plain","subject":"attached"}". So, in order to download image I need to pass attachmentId to GoogleAPIClient and there is no attachmentId in parsed JSON/Model.
Is there a core's method that I should use to get attachmentId?
