Encode short address lease time in minutes or hours

Tag: WGLC

As per discussion at https://bitbucket.org/6tisch/draft-ietf-6tisch-minimal-security/issues/19/concerns-about-the-cojp-message-size-the and during IETF 102:

Encoding address lease time in seconds indeed seems to require much more bytes than needed. We could round this to minutes, or maybe even hours.

lease_time is now in hours, not seconds.
