* rework merkle tree support * rename merkletree -> codexmerkletree * treed and proof encoding/decoding * style * adding codex merkle and coders tests * use default hash codec * proof size changed * add from nodes test * shorte file names * wip poseidon tree * shorten file names * root returns a result * import poseidon tests * update multicodecs * consolidating codex types and adding new codecs * update codec * remove temp codecs constants * move codecs related stuff out * updating codecs * misc * updating sizes since block size was adjusted to 64kb * fix merge issues and cleanup a few warnings
