Abandon project in favour of oomphinc/composer-installers-extender

[derhasi]

With https://github.com/oomphinc/composer-installers-extender there is a package, that provides the same functionality as custom-installer does. The project is also mentioned on https://github.com/composer/installers#should-we-allow-dynamic-package-types-or-paths-no, so it will likely have more attention.

In addition using that package, will avoid running into trouble on global or local installation of composer/installers, like mentioned in composer/composer#5333.

I must slightly agree after I found a bug that's seems to be the same in both projects oomphinc/composer-installers-extender#6 but already got fixed in oomphinc/composer-installers-extender.

I can provide a composer.json to reproduce if you wish. But I just switched to oomphinc/composer-installers-extender.

oomphinc/composer-installers-extender is too large for some small projects, causes 100+ files added.
Its great that this plugin has 12 files only
