• Handle 429 too many requests coming from fuzzysearch
• Delay after too many failed searches on saucenao

• Implement FuzzySearch support

• Removed php-wfio extension support
• Bumped PHP version requirement to 7.2 (will still work with older versions most likely but they are no longer supported)

• Force memory limit to be set to 1GB

• Prevent re-running md5 checks after batch md5 search is done

• Optimization and small changes to MD5 search prefetch functionality

• Prefetch all MD5 searches before doing anything else to speed up everything, uses batch syntax in e621's API

• Updated run scripts to ignore system's php.ini
• No temporary files are created when using conversion or php_wfio extension, everything happens in memory now

• e621 searches now correctly return "no images found" reply

• Add 3-second cooldown for e621's iqdb search when "429 - Too Many Requests" is returned

(Also MD5 check is affected - but only 1-second delay was added)
