Add file property to the ImageAttachmentPayload

[laevandus]

🔗 Issue Links

Resolves IOS-319

🎯 Goal

Fix an issue where ImageAttachmentPayload does not set file_size and/or mime_type

📝 Summary

• Add ImageAttachmentPayload.file and new init method requiring setting file
• Deprecate init(title:imageRemoteURL:originalWidth:originalHeight:extraData:) in favour of init(title:imageRemoteURL:file:originalWidth:originalHeight:extraData:)
• Aligns ImageAttachmentPayload to other attachment payloads which require file to be set

🛠 Implementation

Other attachment payloads require AttachmentFile type when creating a payload. ImageAttachmentPayload is the only one which represents a file, but does not require it. This leads to all the image attachments sent from the iOS SDK to not set file_size and/or mime_type.
