science/py-mercantile: Move science/mercantile to science/py-mercantile

- Change MASTER_SITES from GitHub to PYPI
- Add LICENSE_FILE
- Fix version requirement of RUN_DEPENDS
- Convert to USE_PYTHON=pep517
- Bump PORTREVISION for package change
- Take maintainership

all: return bland@'s ports to the pool (+gnome) after safekeeping their commit bit.

Hat:	portmgr-secretary

all: remove explicit versions in USES=python for "3.x+"

The logic in USES=python will automatically convert this to 3.8+ by
itself.

Adjust two ports that only had Python 3.7 mentioned but build fine
on Python 3.8 too.

science/mercantile: move URL from pkg-desxcr to Makefile

The URL at the end of the pkg-descr file has been moved into the
Makefile for all existing ports.

BTW: The following URL might be a better value for WWW, since it
provides the user of the package with examples information about
the concepts.

    https://mercantile.readthedocs.io/en/latest/

There is also a link to the GitHub reposirory in that text, but
the WWW value is meant to help a user of the port, not to keep
a note about the repository for the maintainer.
