Package heatmap as an installable CLI (that uses docker)

[twelch]

Make it easier to use sap-map. Don't require the user to clone the repo, know docker commands or manage projects inside the src folder. Should be able to just install the tool and use a simple CLI command. And manage config.json files and input/output from the outside

Example install

curl -L https://github.com/seasketch/python-sap-map/archive/main.tar.gz | tar xvz
cd python-sap-map && sudo make install

Example run

heatmap --output /path/to/output --input /path/to/input path/to/config.json

Windows users may be able to use the makefile via WSL2 and possibly utilize Docker support for running containers with WSL2.
