colormag-bxslider: Detect SiteOrigin Page Builder

[AlexGStapleton]

A user of Colormag pro has identified an issue where the Frontpage slider widgets won't work (nothing will appear) as expected when added inside of a SiteOrigin Page Builder instance - SiteOrigin Layouts Block, Layout Builder, SiteOrigin (Widgets Bundle) Layout Slider. I've come up with a fix to this but it appears the underlying code isn't in this repo so I'm not able to submit it. I've included the fix below. I would be happy to submit this fix to any repo, or for someone else to submit it on my behalf.

Open colormag-pro/inc/helper-functions.php and find:

if ( ! function_exists( 'colormag_elementor_active_page_check' ) ) :

	/**
	 * Check whether Elementor plugin is activated and is active on current page or not.
	 *
	 * @return bool
	 *
	 * @since ColorMag 2.2.3
	 */
	function colormag_elementor_active_page_check() {
		global $post;

		if ( defined( 'ELEMENTOR_VERSION' ) && get_post_meta( $post->ID, '_elementor_edit_mode', true ) ) {
			return true;
		}

		return false;
	}

endif;

Add after:

if ( ! function_exists( 'colormag_siteorigin_panels_active_page_check' ) ) :

	/**
	 * Check whether SiteOrigin Page Builder plugin is activated and is active on current page or not.
	 *
	 * @return bool
	 *
	 * @since ColorMag 
	 */
	function colormag_siteorigin_panels_active_page_check() {
		global $post;

		if ( defined( 'SITEORIGIN_PANELS_VERSION' ) && get_post_meta( $post->ID, 'panels_data', true ) ) {
			return true;
		}

		return false;
	}

endif;

Replace every instance of the following conditional:
if ( is_active_widget( false, false, $this->id_base ) || is_customize_preview() || colormag_elementor_active_page_check() ) {

With:
if ( is_active_widget( false, false, $this->id_base ) || is_customize_preview() || colormag_elementor_active_page_check() || colormag_siteorigin_panels_active_page_check() ) {
