Add an argument `-a` to provide a asmap file to do the IP to ASN
lookups.
This speeds up the script greatly, and makes the output deterministic.
Also removes the dependency on `dns.lookup`.
I've annotated the output with ASxxxx comments to provide a way to
verify the functionality.
For now I've added instructions in README.md to download and use the
`demo.map` from the asmap repository. When we have some other mechanism
for distributing asmap files we could switch to that.
This continues #24824. I've removed all the fallbacks and extra
complexity, as everyone will be using the same instructions anyway.

Documentation:
- Use https URL for bitcoin.sipa.be (http sends a redirect, fooling
curl).
- Add explicit step to add manual seeds.
Code:
- Change PATTERN_ONION to v3 (effectively means that the no onion hosts
are delivered).
- Add versions to PATTERN_AGENT filter.
- Print specific message on resolve exception.
44407100f broke inserting entries into addrman from static seeds
(as well as dnsseeds which did not support service bits). Static
seeds were already being filtered by UA for 0.13.1+ (ie
NODE_WITNESS), so simply changing the default service bits to
include NODE_WITNESS (and updating docs appropriately) is
sufficient.
For DNS Seeds, we will later fix by falling back to oneshot if a
seed does not support filtering.
- Moved all seed related scripts to contrib/seeds for consistency
- Updated `makeseeds.py` to handle IPv6 and onions, fix regular
expression for recent Bitcoin Core versions
- Fixed a bug in `generate-seeds.py` with regard to IPv6 parsing
