Sticky scroll doesn't work when not indenting YAML lists

[k8ieone]

In YAML lists can be optionally indented. In case where the list is indented, the plugin works as expected. When there is no list indent, it ignores the list.

Without indents (doesn't work):

list:
- item1
- item2

With indents (works):

list:
  - item1
  - item2

To support this you can add a custom get level function by adding the following to your user module:

core.add_thread(function()

  if config.plugins.sticky_scroll then
    local StickyScroll = require "plugins.sticky_scroll"
    config.plugins.sticky_scroll.filetype_overrides["YAML"] = function(doc, line)
      if string.sub(doc.lines[line], 1, 1) == "-" then
        local _, indent_size = doc:get_indent_info()
        return indent_size
      end
      return StickyScroll.get_level_default(doc, line)
    end
  end

end)

Note

This will not take into account previously badly indented lines, so lines that start with - will always get treated as indented only once.

Not sure if this is material to add on the plugin it self on this list https://github.com/pragtical/plugins/blob/master/plugins/sticky_scroll.lua#L19-L28 If you think so feel free to send a PR with the addition and version bump of plugin on manifest file.
