This PR adds dedicated support for the Markdown Archicturual Decision Records by @koppor and @socadk. A user can now initialize the repository using adr init DIR madr. MADR not only uses a different template.md, but also a different status format (see adr/madr#2). This is necessary, because MADR requires date and status information only when the status is not "Accepted".

We would be happy if this was included in adr-tools as adr-tools eases working with ADRs.

@npryce any update for this pull request?

I'm sorry. I'm not keen on supporting multiple formats. It adds non-trival maintenance overhead to ADR tools, and imposes complication on other tools that process the ADRs managed by adr-tools -- e.g. projects' documentation build pipelines, architecture visualisation tools. etc. Those tools would also have to become aware of the different formats, and how they define links between ADRs.

I'd be happier with multiple formats if there was a way to add formats in a non-intrusive way. E.g. without adding conditional logic that branches on format, and without the implementations of different formats having to be in the same repo as adr-tools itself. That way, each other format could be maintained by people who want to use it.
