Workout messages are not sent with any payload or special information, but contain text that looks like one of:

$(kIMTranscriptPluginBreadcrumbTextReceiverIdentifier) completed a workout.
$(kIMTranscriptPluginBreadcrumbTextReceiverIdentifier) earned an achievement.
$(kIMTranscriptPluginBreadcrumbTextReceiverIdentifier) closed all three Activity rings.

Where I assume $(kIMTranscriptPluginBreadcrumbTextReceiverIdentifier) is some information about the contact that sent the message. All of the BLOB fields are NULL for these messages, so we need to check them when writing the text and replace the contact's phone number in the correct place.

If we can avoid scanning each message as we write them, we should. Perhaps we should preflight and cache the IDs of messages that contain this kIMTranscriptPluginBreadcrumbTextReceiverIdentifier string and cache them like we do other types of message information.

balloon_bundle_id has some app developer metadata and payload_data has some plist data we can look at for specific apps like Apple Pay that contain information useful to the export.

The program generates the following panic when exporting messages:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: Os { code: 63, kind: InvalidFilename, message: "File name too long" }', imessage-exporter/src/exporters/txt.rs:250:14

This appears to happen when a group chat name is concatenated to too long of a string.

• Support edited and unsent iMessages
• Parse streamtyped data for normal and edited messages
• Better error handling throughout app
• Fix indent issue for app messages in txt export

In the payload_data that ends up looking like this escaped html code:

If we got the whole string that would be fine, but iMessage truncates this data, so we end up getting some unclosed tags.

Rendering inside of <pre><code>…</code></pre> ends up rendering all of the escaped HTML, so I used an xmp tag in lieu of a code tag here to render the text properly. Since xmp is deprecated, we should do something else here. Ideally we can avoid using Javascript, as we want these pages to be printable to a PDF, and Javascript opens the door to non-printable features.

ME should be overridden by custom text.

There is an int column in the messages table called item_type. Normal messages are 0, channel announcements that update the room name are 2. I have a third item_type in my database, "aptly" named 4, and it seems to be a fully null message (no text or blob data, no associated message, nothing). What does 4 represent? Is there a 1?
