Add PackageName::as_dist_info_name (#305)

Browse source 
From
https://packaging.python.org/en/latest/specifications/recording-installed-packages/#recording-installed-packages

> This directory is named as {name}-{version}.dist-info, with name and
version fields corresponding to Core metadata specifications. Both
fields must be normalized (see Package name normalization and PEP 440
for the definition of normalization for each field respectively), and
replace dash (-) characters with underscore (_) characters, so the
.dist-info directory always has exactly one dash (-) character in its
stem, separating the name and version fields.
