Update package (#1)

- Add CI, license, and NOTICES
- Update CMustache to the 1.2.6 version of mustach
- Bump Swift requirement to 5.7 and add platform version minimums
- Fix build on Arch Linux
- Remove outdated test files
- Update mustach API usage

The `MustacheTests.testSectionArray` test currently fails. This appears
to have been the case for a long time, and also doesn't appear to affect
the Vapor toolbox's usage.

Arch Linux build was tested manually; build completes cleanly with no
errors or warnings.
