Robin van Boven 7509a78f65 Add --weights as load option (#1224)
Includes a change to `cli/load` and `build_static_site.sh` to accept a `--weights WEIGHTS_FILE` argument.
This allows overriding the default weights at build-time using a `weights.json` that has the same format as previously generated in the frontend.

Test plan:
Adds an additional test-case as well for propagating the optional parameter.
The file I/O of loading and parsing a weights.json file was tested manually. As analysis/weights' fromJSON() is tested elsewhere as is passing weight parameters.
