Limitations and requirements
- no media (yet?)

- filename must exactly and uniquely identify an existing conversation (group or contact name) in the Signal backup
- messages have format '<timestamp><author>: <message>' where timestamp is passed as 'fmt', author exactly
and uniquely identifies an existing contact in the Signal backup and contains no colons (':')
