V2 core features (#22)

* v2.Array create, arrayMetadata and codecPipeline

* v2 and v3 Array implements Array Interface

* documentation for Array methods and improve parameter descriptions

* adopt allocateFillValueChunk() and chunkKeyEncoding()

* zarrita tests with uv

* fix ci

* add zlib

* fix testoutput paths

* split v2 and v3 codecs to fix serialization

* zarr-python tests for v2, v3

* isolate v2 and v3 with common core

* isolate v2 and v3 with common core.chunkkeyencoding

* add zarrita to ci while not removed from tests

* fix zarr-python tests on Windows?

* debug windows CI

* uv add "zarr>=3.1.2"

* use python 3.11

* remove debug changes

* remove v3 code in v2

* change multi-inheritance:
 - codecs in core are abstrac classes
 - parent codec per v2/v3 (used for serialization) is interface

* refactor code duplication
