Merge dashpay#679: Add SECURITY.md

78c3836 Add SECURITY.md (Jonas Nick)

Pull request description:

  Fixes dashpay#646

  WIP because the [email protected] email address doesn't exist yet. But it seems like the right place for vulnerability reports. [email protected] would have the downside that it perhaps reaches more people than necessary. Ideally secp256k1-security would just forward to the three maintainers listed in SECURITY.md. @sipa @apoelstra is it okay to put you there? Fwiw I'm opting out for now because three people should be enough.

  @sipa do you know who to talk to about adding [email protected] and the specifics about how it would work?
