Integrate slot builder (#666)
* 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

* fix merge issues and cleanup a few warnings

* setting up slot builder

* Getting cids in slot

* ensures blocks are devisable by number of slots

* wip

* Implements indexing strategies

* Swaps in indexing strategy into erasure.

* wires slot and indexing tests up

* Fixes issue where indexing strategy stepped gives wrong values for smallest of ranges

* debugs indexing strategies

* Can select slot blocks

* finding number of pad cells

* Implements building slot tree

* finishes implementing slot builder

* Adds check that block size is a multiple of cell size

* Cleanup slotbuilder

* Review comments by Tomasz

* Fixes issue where ecK was used as numberOfSlots.

* rework merkle tree support

* deps

* rename merkletree -> codexmerkletree

* treed and proof encoding/decoding

* style

* adding codex merkle and coders tests

* remove new codecs for now

* proof size changed

* add from nodes test

* shorte file names

* wip poseidon tree

* shorten file names

* fix bad `elements` iter

* bump

* bump

* wip

* reworking slotbuilder

* move out of manifest

* expose getCidAndProof

* import index strat...

* remove getMHash

* remove unused artifacts

* alias zero

* add digest for multihash

* merge issues

* remove unused hashes

* add option to result converter

* misc

* fix tests

* add helper to derive EC block count

* rename method
