The third release candidate for OpenRGB 1.0.  This should be treated as the latest stable build even though it's a release candidate.  This release candidate brings improved device support, bug fixes, and some minor user interface cleanup over the 1.0rc2 release candidate.  With 1.0rc2, we replaced the problematic WinRing0 driver with PawnIO on Windows.  This release candidate brings some improvements to the PawnIO usage, reducing PawnIO CPU usage and adding some usability improvements with the installer prompting users to install PawnIO.  This release candidate fixes two long-standing issues when probing I2C devices that could lead to system instability on some setups.  The PawnIO driver additionally now supports I2C/SMBus on Intel Skylake-X (X299) platforms, allowing RGB RAM control on these systems that did not have support under any previous driver.

This release candidate does not update the plugin API or SDK version, so the 1.0rc2 plugins will still work.  I'm not doing plugin release candidates for this one so keep using the 1.0rc2 versions.

Distro maintainers, please continue using Qt5 for this release candidate.  We will switch to Qt6 with 1.0 final.

Notable device support updates:

- Corsair DRAM controller has been improved so that the module type/name and number of LEDs are determined automatically
- New QMK keyboard support for VialRGB and Keychron protocols
- New Logitech HID++ 2.0 controller should allow for more Logitech device support in the future
- Better support for PNY Epic-X ARGB GPUs
- Rework of Gigabyte motherboard support adds support for many additional boards
- Some new MSI motherboard, laptop, and monitor support
- Lots of GPUs added across various controllers
- Support for Clevo laptop keyboards and lightbars
- Support for some PowerColor GPUs
