Feature description

I see there's a golangci-lint diagnostics source that disables fixing the issues.
I tried overriding the arguments to remove the --fix=false, but it looks like the buffer isn't updated unless I trigger a re-read by e.g. changing focus from and to neovim ; which is quite annoying.

Could it be possible to have a "formatting" source that runs with fixes as well as the current diagnostics source?
