[MetaCRS] Motion: Promote PROJ 5.0.1RC1 to final release

[Kristian Evers]

All,

I motion to promote PROJ 5.0.1RC1 to final release.

As announced previously, this is strictly a bug fix release in the wake of the
massive update that was 5.0.0. 5.0.1 fixes several issues that is considered
blockers by some of the downstream projects. Most notable is that
transformations to and from the Web Mercator again works as expected.

I’ll start with my +1.
