don't try to find forward links in non-text files

Browse source 
If a file extension is not in 'denote-file-types', we have no way of
parsing or finding outgoing links in it. This change checks for the
file extension early on in 'when-let*' block and avoids opening the
file which is a relatively costly operation (and would fail finding
links anyway).
