[tz] Fwd: Bulletin C number 58

[Tim Parenti]

NIST's leap-seconds.list was finally updated today.  Patch attached.

I'd reached out to Christian Bizouard of IERS a bit ahead of the
announcement in the hopes that we could settle the outstanding issues from
2017 with adding a public domain copyright notice to the IERS version of
the file, but no luck this time around.
