Add handling of unexpected end of data stream

[wstrzalka]

Hi

This is proposal to fix the issue #80 raised by me some time ago.
It adds extra hook BlockReaderAdapter::failure(Exception ex) with option to either handle in the adapter or rethrow the exception.

In #80 you talk about a broken input stream. Under which condition is the stream broken?

[wstrzalka]

That may happen for example if you stream the pbf from the network (from some REST endpoint or S3).
The above patch is unfortunately broken though as InputStream.available() doesn't guarantees to return 0 only if there are no more bytes to read.
