added Go dependency cache to go.yml workflow, and go test now covers the full codebase (#53)

* added Go dependency cache to go.yml workflow

* more windows path issues

* docs

* restricting workflow triggers to master

* wrong cleanup order for downloaded files

* de-restricting workflow triggers, for now

* more out-of-order cleanup issues that only manifested on windows

* more out-of-order cleanup issues

* removed mediatype check from TestFetchFile; FetchFile is deprecated and not worth fixing

* tracked down out-of-sequence close/remove issue with sqlite

* probably long-running test failure

* disabling long-running tests that are breaking CI

* switching to go test -short because tests seem to be taking too long in CI
