refactor: deprecate Quant\Core\Trait\AccessorTrait and related PHP-Attributes #35
Description
To provide a leaner package containing only the AccessorTrait and related attributes, Quant\Core\Trait\AccessorTrait, Quant\Core\Attribute\Accessor, Quant\Core\Attribute\Getter and Quant\Core\Attribute\Setter will be deprecated, moved to Quant\Accessor and then removed from their original package.
- soft deprecation in quant-php 1.1 (add @deprecated annotation to the trait and attributes)
- deprecation in quant-php 2 (using the trait and attributes will trigger a deprecation)
- removal in quant-php 3
