This release adds a couple of tests, that fall in two categories:
Legacy SUPER-CHIP tests
We ran into the issue that SUPER-CHIP actually enabled the vBlank quirk in lores mode. This made the test suite fail on the original interpreters on real HP calculators. Adding a "legacy SUPER-CHIP" mode fixes these problems, and makes the quirks test more rigorous for other platforms too.
New tests
This release also adds tests for scrolling and beeping. In the scrolling test we have also had to introduce a "modern" and a "legacy" SUPER-CHIP version of the test.
