Packagist and maintenance status

[defr]

This is kinda a mix of #11 , #4 and #12 but trying to check what's the best way forward here.

First, the current status :

• From Status of this project #11 it looks like this project isn't maintained anymore
• From Add package to packagist #4 though, the source code in this project was added to packagist under the name marlon-be/marlon-sips
• There's actually a fork on github at marlon-be/marlon-sips, which does include a lot of additionals commits and releases. No one using composer is actually getting them though, because the package points here.

Not sure what's should be done about it, but I guess either the package on packagist should be altered to point towards the marlon-be fork instead of this one (pinging @FabriZZio for that, because he's the maintainer on packagist), or this project should definitely merge at least #12 and make a new release, to avoid all the users of the composer package having a broken site once the domain change is in action.
