buffered-reader, openpgp: Change the default buffer size.
- Change the default buffer size from 8 KB to 32 KB.
- Benchmarking using the chameleon reading a 23 MB cert-d with about
800 certificates, and verifying a signature over a short (2 KB)
message, showed that 32 KB is optimal. In particular, 16 KB and
64 KB buffer sizes were, respectively, 10% and 30% worse.
