[PRQ#45149] Deletion Request for python-pysha3

MarsSeed [1] filed a deletion request for python-pysha3 [2]: Discontinued since 2017. [a] It is part of Python 3.6+ from 2016 onwards. A few unmaintained, unused packages still declare it as depends. But it's safe to delete: all maintainers have been notified. One orphan consumer is pending deletion.
