Use wp_get_upload_dir() instead of wp_upload_dir() during plugin bootstrap

[kasparsd]

During the plugin bootstrap logic in wp-shortpixel.php calls wp_upload_dir() which determines the path of the uploads directory for the current month and attempts to create it whenever a new month rolls over.

Line 64 in 5fd9ac3

$sp__uploads = wp_upload_dir();

This logic is triggered on every pageload of the site when the plugin file is loaded and will create new directories even for months when no new files were uploaded.

Consider switching to wp_get_upload_dir() which returns the same data but doesn’t do the file operation.

Alternatively, consider delaying the call to any of these functions (in bootstrap logic in general) until the data is actually needed for the first time (when rendering an image).
