Investigate compiling 3em executor into web assembly.

[andreespirela]

We want to investigate compiling 3em executor into web assembly. So this won't only be used as a CLI, but also as a Web API for browser, nodejs and Deno, or any other runtime that supports web assembly.

Ready when

• Investigation is complete: Whether it is or it is not possible.

Possible refers to

• Same input in the CLI leads to the same output in web assembly.
• Smartweave globals (ops) are respected.
• It's viable to run 3em in web assembly (performance wise, and size of the module wise)

Tagging @t8 for accountability as he was interested in this.

@t8 Opened 2 other tickets too, in case you'd like to take a look

Seperate checklist for this:

• Investigation is complete: Whether it is or it is not possible. (It is.)
• Same input in the CLI leads to the same output in web assembly. (See JavaScript library for 3em js executor #53)
• It's viable to run 3em in web assembly (performance wise, and size of the module wise)

Pretty fast. Only EVM is compiled to WASM. JS and WASM executors are hand written in JS.

• Smartweave globals (ops) are respected.
