Update to handlebars v4.7.6

Currently using using my fork: https://github.com/jbboehr/handlebars.js/tree/remove-equals-4.x
Awaiting PR: handlebars-lang/handlebars.js#1683

* Rewrote everything in TypeScript
* Switched the license to `AGPL-3.0-or-later`. The specification data is still licensed under the `MIT` license, as it is extracted from `handlebars.js`
* `description` now includes all `describe($description, ...)` from the handlebars test suite
* `exception` can now be either `true`, a string, or a regex.
* `message` used to be the exception message, but will now be any extra message noted in the handlebars.js test suite
* `options` was renamed to `runtimeOptions` to differentiate from `compileOptions`
* Using a new version format `104.7.6` which is: `(myMajor * 100 + handlebarsMajor) + '.' + (myMinor * 100 + handlebarsMinor) + '.' + (myPatch * 100 + handlebarsPatch)`
* `number` is now included in tests (besides the first implied `00`) that have multiple cases
* `compat` is removed in favor of `compileOptions.compat`
* `globalPartials`, `globalDecorators`, and `globalHelpers` are now removed and merged into
  `partials`, `decorators`, and `helpers` instead

Closes #7
