TagDeserializer deserialization logic refactored (and cleaned up) into the following classes, which extend BaseTag (as opposed to their previously being accommodated as GenericTags).

Eachs' deserialization is now polymorphic (i.e., deserialization logic is implemented by each class as per its specific need):

  nostr-java-event/src/main/java/nostr/event/tag/EventTag.java
  nostr-java-event/src/main/java/nostr/event/tag/GeohashTag.java
  nostr-java-event/src/main/java/nostr/event/tag/HashtagTag.java
  nostr-java-event/src/main/java/nostr/event/tag/NonceTag.java
  nostr-java-event/src/main/java/nostr/event/tag/PriceTag.java
  nostr-java-event/src/main/java/nostr/event/tag/PubKeyTag.java
  nostr-java-event/src/main/java/nostr/event/tag/RelaysTag.java
  nostr-java-event/src/main/java/nostr/event/tag/SubjectTag.java

additionally:

• GenericTag additional constructor with List parameter (as opposed to just variad String...) and cleanup.
• unit tests for all the above
