Update static seeds

[patricklodder]

Updates static seeds for 1.14.7.

Entries were discovered through network peer exchange, no DNS server was used to reduce potential bias.

Conditions applied to discovered peers:

• must have an up-to-date protocol version and perform handshake properly (because otherwise they will be disconnected before getaddr)
• must have up-to-date addr processing logic and respond to getaddr (because that's all we need them to do)
• any evidence of non-standard behavior or being at max capacity lowers inclusion priority

I've limited mainnet to 250 seed nodes.

To test (on command line linux):

This facility provides your node with peers regardless of the dns servers being reachable.

1. delete ~/.dogecoin/peers.dat (~/.dogecoin/testnet3/peers.dat for testnet)
2. make sure that there is no addnode in dogecoin.conf
3. run dogecoind with -dnsseed=0 -onlynet=ipv4 to test ipv4 seeds; make sure it connects to peers
4. run dogecoind with -dnsseed=0 -onlynet=ipv6 to test ipv6 seeds; make sure it connects to peers

Tested on x86-64 Linux with the following procedure (for both mainnet and testnet)

• Removed peers.dat and any addnode directives
• Built this commit from source with build-unix.md
• ./dogecoind -dnsseed=0 -onlynet=ipv4 (connects to peers properly)
• ./dogecoind -dnsseed=0 -onlynet=ipv6 (connects to peers properly)

All runs had the following output before connecting properly:
