Option to adjust sitemap post limit

[sybrew]

The sitemap currently limits its output to 1200 of posts, pages, and CPT.
Some users want this value increased, and there's a filter for it.

add_filter( 'the_seo_framework_sitemap_post_limit', function( $default = 1200 ) {
	return 14000;
} );

However, after a few dozen requests, I'll just turn it into an option.
The option should yield all post types combined, instead of split. The maximum should be set to 50,000.

Monitor has a check for whether the sitemap exceeds the URL and size (10 MiB) limit.

Moved to a later version. There's too much overhead.

Found culprit. Moved to 3.1.0 again 👍
