Massive refactoring of Quartz to:

- Define each tag in their own class.
- Allow extension functions to additional responsibilities to other classes
- Migrate from hardcoded tag filters in events to the Tag's parser and assemble functions.
- Migrate hardcoded event.create to builders that use extension functions
- Restructures threading infrastructure for NIP-10
- Decouple the event signing from the Event building functions via event templates
- Create classes to represent Tags and TagArrays and use extension functions to add domain-related methods to the tag array of each nip.
- Uses external functions on event template builders to better point to which functions and which tags can be used in which event kinds.
- Separates Event kinds in packages inside each nip.
- Improves support for NIP-89
- Correctly establishes which imeta params can be used in each nip (video, picture, files)
- Decouples the iMeta builder from any nip.
- Fixes mute list word and user removal when inserted from a different client.
- Migrates the Account class to avoiding having to build each Event inside of it

         """Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.
