Rust implementation of dtn bundle protocol 7 draft https://tools.ietf.org/html/draft-ietf-dtn-bpbis-13

This library only handles encoding and decoding of bundles, not transmission or other processing of the data.

This is more or less a port of the dtn7 golang implementation: https://github.com/dtn7/dtn7

**This code is not production ready!**

## Benchmarking

A simple benchmark is shipped with the library. It (de)serializes Bundles with a primary block, bundle age block and a payload block with the contents (`b"ABC"`). This benchmark can be used to compare the rust implementation to the golang, python or java implementations.
