Access to dependency versions at runtime

[ii14]

Maybe plugins should have some standard way of accessing versions of their dependencies to handle differences in API and behavior between versions?

Example:

packspec["telescope"].version
-- returns a string, eg. "1.2.3"

if packspec["telescope"].is("~> 2.0") then -- format reused from "version" field in the spec
  -- ...
else
  -- ...
end

I think this is a duplicate of #3

Not quite, I think the idea there was to have multiple versions of the same plugin at the same time. This is about plugins being able to check the version of their dependencies. I guess this could be a different approach to that problem.
