Compare performance of the LeanIMT written in JS and Rust in Node.js and browser

[vplasencia]

Description

There is an implementation of the LeanIMT data structure in TS/JS: https://github.com/privacy-scaling-explorations/zk-kit/tree/main/packages/imt.

There is no LeanIMT implementation in Rust yet. Once the issue related to the LeanIMT implementation in Rust (privacy-scaling-explorations/zk-kit.rust#51) is closed as completed, there will be a crate for the LeanIMT.

The idea of this issue is to compare the performance of LeanIMT written in TS/JS and Rust (compiled to wasm) in Node.js and browser.
