+- update to version 20180504:
+ * scamper:
+  * increase the size of a buffer in scamper's traceroute json
+    creation to reduce chance of truncation.
+  * print the number of probes sent by traceroute in the json
+    output.
+  * enforce a minimum firsthop value of 1 when reading a warts
+    traceroute object.
+ * sc_bdrmap:
+  * choose a static ICMP checksum value when using Paris traceroute
+    to reduce churn in observed topology in bdrmap output.
+  * add ability to pass list of ASes to -d traces to see
+    traceroutes towards specific ASes, useful for understanding
+    bdrmap inferences.
