Support for reading comments about clj-yaml HOT 2 OPEN

OK, PR welcome to see what can be done about it. Please also add a test :)

from clj-yaml.

I have played around with the options - something is happening - for example when parsing the list-yaml in the tests I get a exception as there is an open issue in Snake yaml for a comment in that position. What I found is that setting the option does not change the output at all. There is a line in one of the snakeyaml files that says:
while (scanner.checkToken(Token.ID.Comment)) { // TODO: till we figure out what todo with the comments scanner.getToken(); }

Which does not give me any confidence that the comments will end up somewhere. There is also an old issue where the devs just say that the comment is over-ridden by the node that comes next.

Shame. Would appreciate someone else confirming this.
