Count $DEGEN in thread

degen.js

if (threadHash) {
          const casts = await util.getAllCastsInThread(threadHash);  // calls Neynar API to fetch all replies to a cast
          var count = 0;
          var regexp = /\b([0-9]+) \$degen\b/i;
          for (var i = 0; i < casts.length; i++) {
            //console.log("count", count);
            var cast = casts[i];
            if (cast.parentHash == threadHash) {
              var text = cast.text;
              if (regexp.test(text)) {
                var match = text.match(regexp);
                count += parseInt(match[1]);
              } // if regexp
            } // if parentHash
          } // for
          frame.imageText = `This thread has received
${count.toLocaleString('en-US')} $DEGEN`;
        }

Note this only counts tips in direct reply to the cast. In other words, if someone replies to a reply with a tip, then the tip goes to the replier and not the original caster, so we don't count.
