New DANE TLSA monitoring/diagnostic utility

[Viktor Dukhovni]

I am pleased to offer to the DANE user community a new monitoring
and diagnostic utility.  This is a one-shot variant of my survey
code specialized for monitoring cron jobs and troubleshooting.

Code and instructions at https://github.com/vdukhovni/danecheck

While Haskell may be an unfamiliar programming development toolchain
for many of you, I hope that it will not be difficult to install it
for the purpose of compiling an existing project.  See the README.md
for build instructions.

Enjoy.
