chillerlan/php-settings-container 2.1.6

on GitHub

• SettingsContainerAbstract::toJSON() will now always throw a JsonException on error, regardless of the given $jsonOptions
• SettingsContainerAbstract::toArray() now runs the object values through the magic getter (as it always should have)
• added explicit nullable types to several method parameters
• added declare(strict_types=1)
• switched static analysis from phan to phpstan (see chillerlan/php-qrcode#277)
• CI & dependency updates

(backport of v 3.2.x except for serialize support)
