Template roots don't render with initial loads for static exporting, sometimes

[arctic-hen7]

Describe the bug
Right now, perseus export will generate templates that have many pages in a rather strange way (actually quite unintended, just a quirk of the system). Let's say we have a template docs, which has a root page and a ton of other subpages. Those subpages will all be exported into a docs/ folder, which is logical, but the root page won't be at docs/index.html, it'll be at docs.html (outside docs/). Unfortunately, different systems handle this in different ways, though most simply won't find the /docs page. Note that the subsequent loads system works fine because the internal Perseus structure is expected to work like this.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://arctic-hen7.github.io/perseus/en-US/docs/ to see this in production.
   or
2. Go to https://arctic-hen7.github.io/perseus and click on the Docs link, which will work.

Expected behavior
Template roots should be rendered in the template's folder as index.html for the initial loads system, and such pages should be able to be rendered.

Screenshots
If applicable, add screenshots to help explain your problem.

Environment (please complete the following information):

• Perseus Version: v0.3.0-beta.17 (affects all versions since exporting was introduced though)
• Sycamore Version: v0.6
• OS: Ubuntu
• Browser: Firefox
• Browser Version:93

i'm facing the same issue, but not with export. i.e links placed in index.html do not render unless i manually specify them in .head()

That's a very different issue I think. Here, I'm just talking about some pages not rendering properly when exported.

ok

I've fixed this by placing all initial load pages into their own directories when exporting. That shouldn't result in any changes to the vast majority of codebases, and this should improve compatibility with a wider variety of hosting systems.
