Add support for new p/ data structures

[Kouteki]

Description

Add support for more optimal data structures:

• 'binary slice'
• 'Merkle tree'
• 'logN-gas binary tree'

Each data structure should have:

• A benchmark suite
• Accompanying documentation

The structure list is not definite; if you have a proposal for another data structure, and/or you're willing to implement it, use this issue to discuss it.
