Future maintenance of bmx

[philipnbbc]

I have decided to retire at the end of this month. That means I will no longer be maintaining and updating bmx as I've been doing for the past decade. There have been many welcome contributions over the years but the majority of the contribution review and general maintenance have still been down to me to do. We (now @thomasheritage and BBC R&D) are interested to discuss with the community about the future of the project, how it could be maintained as a minimum and potentially extended in the future.

The intention is to keep the repository as it is now for at least 6 months to allow the discussions to be had and thereafter decide whether the repo should be archived or not. Any bugs or PRs during that period will likely not be processed as it currently stands.

If you have any thoughts on what direction this project should take, how it could be maintained and developed (e.g. creating releases, build system improvements, code review, fixing bugs, testing and developing new features) or potential help you could provide in different aspects of the project then please respond in this issue.
