devel/hs-bytebuild: import hs-bytebuild-0.3.16.3

This is similar to the builder facilities provided by
Data.ByteString.Builder. It is intended to be used in situations where the
following apply:

* An individual entity will be serialized as a small number of bytes (less
  than 512).
* A large number (more than 32) of entities will be serialized one after
  another without anything between them.

Unlike builders from the bytestring package, these builders do not track
their state when they run out of space. A builder that runs out of space
simply aborts and is rerun at the beginning of the next chunk. This strategy
for building is suitable for most CSVs and several line protocols (carbon,
InfluxDB, etc.).
