Creates a new Attachment

Examples:

Attachment.new("/path/to/attachment.png")
Attachment.new("/path/to/attachment.png", filename: "image.png")
Attachment.new("/path/to/attachment.png", filename: "image.png", content_type: "image/png")
Attachment.new(params["file"]) # Where params["file"] is a %Plug.Upload
Attachment.new({:data, File.read!("/path/to/attachment.png")}, filename: "image.png", content_type: "image/png")

Examples with inline-attachments:

Attachment.new("/path/to/attachment.png", type: :inline)
Attachment.new("/path/to/attachment.png", filename: "image.png", type: :inline)
Attachment.new("/path/to/attachment.png", filename: "image.png", content_type: "image/png", type: :inline)
Attachment.new(params["file"], type: :inline) # Where params["file"] is a %Plug.Upload
Attachment.new({:data, File.read!("/path/to/attachment.png")}, filename: "image.png", content_type: "image/png", type: :inline)

Inline attachments by default use their filename (or basename of the path if filename is not specified) as cid, in relevant adapters.

Attachment.new("/data/file.png", type: :inline)

Gives you something like this:

<img src="cid:file.png">
