6abe772a17e09fe96e68cd3311280d5a30f6378b contrib: Add asmap-tool (Fabian Jahr)
Pull request description:
This adds `asmap.py` and `asmap-tool.py` from sipa's `nextgen` branch: https://github.com/sipa/asmap/tree/nextgen
The motivation is that we should maintain the tooling for de- and encoding asmap files within the bitcoin core repository because it is not possible to use an asmap file that is not encoded.
We already had an earlier version of `asmap.py` within the seeds contrib tools. The newer version only had a small amount of changes and is still compatible, so the old version is removed from contrib/seeds and the new version is made available to `makeseeds.py`.

Seeds
Utility to generate the seeds.txt list that is compiled into the client (see src/chainparamsseeds.h and other utilities in contrib/seeds).
Be sure to update PATTERN_AGENT in makeseeds.py to include the current version,
and remove old versions as necessary (at a minimum when SeedsServiceFlags()
changes its default return value, as those are the services which seeds are added
to addrman with).
The seeds compiled into the release are created from sipa's DNS seed and AS map
data. Run the following commands from the /contrib/seeds directory:
curl https://bitcoin.sipa.be/seeds.txt.gz | gzip -dc > seeds_main.txt
curl https://bitcoin.sipa.be/asmap-filled.dat > asmap-filled.dat
python3 makeseeds.py -a asmap-filled.dat -s seeds_main.txt > nodes_main.txt
cat nodes_main_manual.txt >> nodes_main.txt
python3 generate-seeds.py . > ../../src/chainparamsseeds.h
