customHeaders
TypeScript
get customHeaders(): Array<MMSPartContent_MMSCustomHeader>

For file attachments, this can be the file contents in binary.
> Tip: When sending an MMS message that includes text, convert the text string to a <doc://com.apple.documentation/documentation/foundation/data> instance; for example, `let textData = myString.data(using: .utf8)`.
