Deprecation of the library

[priv-kweihmann]

Due to #184, which is now open for months and still no visible change is anywhere close, publishing new releases of this library doesn't make sense anymore.

It was fun while it lasted, but beside spamming my inbox there is no use waiting for something that will likely not happen.

For users we strongly suggest to take a look at

for a better maintained solution of compliance data
