Two experimental features + version bump before release

- `aaa-z` and `a-zzz` sort orders (uppercase first, alphanumeric order and lowercase  first, alphanumeric)
- `vsc-unicode` sort order, which is equivalent to what VS Code refers to as 'unicode' sorting (which name is arbitrary and confusing, yet familar to VS Code users)
