This adds the latest_asmap.dat result for the coordinated launch from #42 for epoch 1770307200. We had a match from 9/14 participants in the coordinated launch.

The sha256 hash after encoding the file are:

filled (encoded with --fill) / latest_asmap.dat: 1d7555ea942c95a89607daa0a3a3fb014b1f728fbb77cce7cb1f85ee9a617597
unfilled 6ad4cda85b6563f47868d577cf577261d21782b0566a78b0e3ab57659718edee
To confirm the result of the encoding you can use asmap-tool.

Between this month and last, the unfilled map changed 0.6% and the filled map changed 13%, by count of IPv4 addresses. The difference is to be expected, since the fill procedure reassigns gaps randomly.
