Updated build system & new maintainers

[ErisDS]

Hello SQLite3 users 👋

Since creating this repo, Mapbox have done an incredible job maintaining it, including hosting (at their own cost) the builds that have made the sqlite3 package such a breeze to install for most environments. Ghost have had a great relationship with Dane and the Mapbox team as we've been so dependent on the library and are very grateful for all the support they've given us through their work on this repo.

Ghost are taking over stewardship of the repository and package, giving particular care to ensuring that the builds continue to work as seamlessly as they did previously. In order to facilitate this, the repository has moved under the TryGhost org so that we have all the permissions we need to maintain the build system.

We're really grateful to Mapbox, and @kewde and all the other people who've been actively involved in looking after the repo until now and we are very keen to keep working with all who wants to contribute going forward.

@daniellockyer will be taking point on ensuring the package builds smoothly, and keeping up-to-date with changes to sqlite3, dependencies and any security issues. He has already fixed up an issue caused by the change from python 2 to 3, using xPaw's PR to swap part of the system from using python to node & also moved the builds from s3 to GitHub. Anyone who has had problems installing SQLite should try again using the latest version.

We're also going to work through all the open issues and PRs to try to clean up a little & add some more tooling to help keep the repository maintained.

We're really excited to be able to take the repo & package forward 😊
