[Bug] DiffviewGlobal is nil

[lewisdiamond]

Description

Is diffview.lib is require()d without having imported diffview.bootstrap first, diffview crashes attempting to index a nil value.

Expected behavior

requiring bootstrap should not be necessary for using lib. For example: https://github.com/harrisoncramer/gitlab.nvim/blob/96d7e16ef7b26e42fdf813fd32f39d096aed33e1/lua/gitlab/reviewer/init.lua#L12

Actual behavior

diffview/lib.lua:12: attempt to index global 'DiffviewGlobal' (a nil value)

Steps to reproduce

1. require("bootstrap.lib")
