Merge #881: update to darkscience tor address v3

1125120bb2 darkscience tor address v3 (unofficial bisq contributor)

Pull request description:

  darkscience actually already running a v3 address, just the [website ](https://www.darkscience.net/servers/) is~~n´t~~ updated ~~yet~~. You can try
  `darksci3bfoka7tw.onion` -> `darkirc6tqgpnwd3blln3yfv5ckl47eg7llfxkmtovrv7c7iwohhb6ad.onion`

  And the tor version works reliably for me lately.

  Verify yourself by:

  `torsocks openssl s_client darkirc6tqgpnwd3blln3yfv5ckl47eg7llfxkmtovrv7c7iwohhb6ad.onion:6697`

  > `:irc-eu-1.darkscience.net NOTICE * :*** Could not resolve your hostname: Malformed answer; using your IP address (127.0.0.1) instead.`

  `openssl s_client irc-eu-1.darkscience.net:6697 | openssl x509 -fingerprint | grep Fingerprint`

  ```
  depth=2 O = Digital Signature Trust Co., CN = DST Root CA X3
  verify return:1
  depth=1 C = US, O = Let's Encrypt, CN = R3
  verify return:1
  depth=0 CN = irc-eu-1.darkscience.net
  verify return:1
  SHA1 Fingerprint=97:88:24:3D:1B:25:55:61:D3:01:92:1A:5E:66:4D:47:07:23:B1:C4
  ```

  compared same for:

  `torsocks openssl s_client darkirc6tqgpnwd3blln3yfv5ckl47eg7llfxkmtovrv7c7iwohhb6ad.onion:6697 | openssl x509 -fingerprint | grep Fingerprint`

  ```
  depth=2 O = Digital Signature Trust Co., CN = DST Root CA X3
  verify return:1
  depth=1 C = US, O = Let's Encrypt, CN = R3
  verify return:1
  depth=0 CN = irc-eu-1.darkscience.net
  verify return:1
  SHA1 Fingerprint=97:88:24:3D:1B:25:55:61:D3:01:92:1A:5E:66:4D:47:07:23:B1:C4
  ```
