consume extracted paramfetch + basic CircleCI config (#63)

* consume newly-extracted go-paramfetch * add basic CircleCI config, and use TestDownloadParams to hydrate cache before running tests * make deps, not make deps lotus * use Makefile target when testing + set env variable for verbose rust logging * drop gosumtest * drop short mode * add some documentation
