Tests should be able to run across platforms without much customization, currently each platform provides a custom [name](https://github.com/consento-org/get-random-values-polypony/blob/main/test/implementation.js#L14) variable.

We should have some way to work around this.

**Describe the solution you'd like**
A clear and concise description of what you want to happen.

Either remove it, or provide separate entry points for tests per platform

**Additional context**
Add any other context or screenshots about the feature request here.

Start with test/implementation.js, especially the platform-specific name variable referenced in the issue, and inspect how the tests use it across platforms. Determine whether removing that variable or adding separate platform entry points fits the existing setup; done means the tests run across platforms without custom name configuration.
