v0.13.0

• Updated winit version to 0.30.
• Changed WinitPlatform::init to WinitPlatform::new and deprecated init.
• Fixed double key-presses on certain platforms.

This also marks the first release where imgui-winit-support is outside the imgui-rs monorepo!

As a note: this release did not contain a bump in imgui-rs version.
