This reverts the changes commit 24928c6f did beyond mere type fixes to
pkg_relations(). It looked better, but it had the output collapse to
an empty list. Refactoring of that mega-function postponed.

BaseCmdPkgRelations contains pkg_relations(), a function doing
package graph analysis code. The function needs to be made available
to code outside BaseCmdPkgRelations, so move it to
cmds.projects.lib.pkg_relations.
The commit also applies style fixes to both BaseCmdPkgRelations and
pkg_relations which anticipate broader style changes to jw-pkg in
general.

Add tmpl_render(), a function to provide a primitive template
renderer. It takes a dictionary for values to replace variables
shaped {some-variable} in templates found by their name. For now, the
templates are defined in the templates module instead of being read
from a template directory. The values may be lists, in which case
they are rendered with a delimiter, defaulting to ",".
Using an existing template engine like jinja2 is tempting but would
introduce additional dependencies jw-pkg is trying hard to avoid.

Add a sub-module for code that's too specific to jw.pkg.cmds.projects
to go into jw.pkg.lib but too generic to go into a command module.
Long-term, it might be a good idea to create a place for code which
jw-pkg doesn't exclusively use for its own purposes. jw.lib, for
example. Then, liberated from the burden to be generally useful also
externally, jw.pkg.lib might be a better fit for code currently in
jw.pkg.cmds.xxx.lib, and a more natural place usable across
subcommands.
