Delta compression algorithm from fossil SCM

# Delta compression algorithm for python

> > This is a python wrapper of the original C implementation. (Source code from Fossil-2.6)

Fossil achieves efficient storage and low-bandwidth synchronization through the
use of delta-compression. Instead of storing or transmitting the complete
content of an artifact, fossil stores or transmits only the changes relative to
a related artifact.

```

## Example

```python
