Introduce ReactionTypeable interface

[antonkomarev]

Follow up to the Interface Segregation Principle violation fix PR #1

I propose to extract ReactionTypeable interface from Reaction & ReactionCounter models. It will be a breaking change.

interface ReactionTypeable
{
    public function getReactionType(): ReactionType;

    public function isOfReactionType(ReactionType $type): bool;

    public function isNotOfReactionType(ReactionType $type): bool;
}

$reactionType = $reaction->getReactionType();
$isTrue = $reaction->isOfReactionType($reactionType);
$isFalse = $reaction->isNotOfReactionType($reactionType);

$reactionType = $counter->getReactionType();
$isTrue = $counter->isOfReactionType($reactionType);
$isFalse = $counter->isNotOfReactionType($reactionType);

Current implementation

1. Methods from the Reaction model doesn't have reaction word because initially I've thought that it's redundant:

public function getType(): ReactionType;

public function isOfType(ReactionType $type): bool;

public function isNotOfType(ReactionType $type): bool;

2. Methods from the ReactionCounter model:

public function getReactionType(): ReactionType;

public function isReactionOfType(ReactionType $type): bool;

public function isNotReactionOfType(ReactionType $type): bool;

New generic method	Current Reaction method	Current ReactionCounter method
getReactionType	getType	getReactionType (same)
isOfReactionType	isOfType	isReactionOfType
isNotOfReactionType	isNotOfType	isNotReactionOfType
