Sorting results with org-ql-block

[acosmicjoke]

I noticed that org-ql-block doesn't allow sorting the query results. It doesn't accept a :sort argument and ignores the value of org-agenda-sorting-strategy . I use org-ql only through custom agenda commands, and lacking this feature makes it pretty inconvenient. org-ql-block seems to be using org-ql-select internally, which already knows how to sort results, so this sounds pretty easy to implement.
