Bugfix release for Emacs 30.1

What's fixed

• Fixed issue with errors, including ert errors, being swallowed in turtles-with-minibuffer on Emacs 30.1
• Improved subprocess cleanup, to avoid leaving running subprocesses after the main Emacs has finished

Full Changelog: 2.0.0...2.0.1

NEW Turtles test are now started with turtles-ert-deftest, to avoid side-effects when loading turtles.el.

This is a small, but backward-incompatible change, so requires a major version bump.

To keep your tests stable, please depend on either the tag 2.0.0 or the branch 2.0.

Full Changelog: 1.0.0...2.0.0

This is the initial release of Turtles, a package help write ERT-based tests to that check how Emacs renders buffers and windows. The ERT tests can be run interactively or in batch mode.
