This commit takes aims to bring many new garmin devices up to a working status, with basic functionalities such as:
- garmin protocol initialization
- basic message exchange
- support for some messages in Garmin own format
- support for some messages in protobuf format
Also use the named column indexes instead of numeric ids when retrieving the contents to make it more clear and more robust in case further fields are added later.
Reminders are set as absolute timestamp.
