bytestring-strict-builder-0.4.5: An efficient strict bytestring builder

According to the competition benchmarks, this library provides on average the fastest builder of strict bytestrings.

Practical benchmarks have proven it to be highly performant as well. The encoders from the "postgresql-binary" library have shown a stable performance improvement by factors of up to 10 after the migration from the standard builder to "bytestring-strict-builder".
