Decouple step to create dwellings assignment

[dhixsingh]

To create the dwellings assignment for a given SA2, the script should take as input:

• A households CSV for the SA2
• LandVic property addresses file(s) that includes the SA2, and
• A mapping from SA2 to the Landvic "regions".

The output should be a households assignments (JSON) to known addresses in that SA2.

Refer to notes in #22.

This is fixed as of commit ff3bccb

To map Vicmap addresses to SA1s and then assign households to addresses run java -jar addressmapper/target/addressmapper.jar addressmapper.properties -sh command from synthetic-population/populationbuilder directory. This program uses the population files generated with synthesis.jar, so the population must be synthesised prior to running this command.

To map addresses to SA1s without mapping households use -s command line argument instead of -sh.

If addresses are already mapped to SA1s, households can be assigned to addresses (dwellings) independently by specifying only -h.
