/**
* Hacky workaround for #96.
* For {@link PGPPublicKeyRingCollection#PGPPublicKeyRingCollection(InputStream, KeyFingerPrintCalculator)}
* or {@link PGPSecretKeyRingCollection#PGPSecretKeyRingCollection(InputStream, KeyFingerPrintCalculator)}
* to read all PGPKeyRings properly, we apparently have to make sure that the {@link InputStream} that is given
* as constructor argument is a {@link PGPUtil.BufferedInputStreamExt}.
* Since {@link PGPUtil#getDecoderStream(InputStream)} will return an {@link org.bouncycastle.bcpg.ArmoredInputStream}
* if the underlying input stream contains armored data, we have to nest two method calls to make sure that the
* end-result is a {@link PGPUtil.BufferedInputStreamExt}.
*
* This is a hacky solution.
*
* @param inputStream input stream
* @return BufferedInputStreamExt
