devel/py-future: Update version 0.18.3=>1.0.0

• Mark DEPRECATED
• This port has outlived it's purpose. It has been more than 6 years python 2.7 has reached EOL and by now all of the coded has been converted to be compatible with python 3.X
• There are still some ports using this port but after checking I have found that those are stale dependencies as maintainers do not properly check upstream requirements or the ports are no longer maintained upstream.
• I am reaching out to the maintainers if these are stale dependencies
• I am reaching out to the maintainers if there are trivial fixes to remove these depencies
• Set EXPIRATION_DATE 2026-09-30 for the 2.7 flavor and 2026-12-31 for the 3.X flavor. We will reconsider the EXPIRATION_DATE for the 3.X flavor before the end of the year
