Show signs only in number column

With the setting `g:ale_sign_highlight_linenrs` set to 1, you can enable ale to display errors in the number column. This setting works, but ale still shows signs in the sign column as well.

Is there a setting to display the errors only in the number column?

If not I'd like to suggest a setting like `g:ale_sign_highlight_signcolumn` which controls displaying the errors in the sign column without disabling sign-display completely.
