Fix Testing Framework in the JSOO build

prometheansacrifice requested to merge prometheansacrifice@ligojs-testing-framework into dev

Motivation and Context

ligo.js doesn't have a working testing framework.

Description

This MR uses a patched version of protocol to let us use it for the testing framework.

Protocol is written with 64-bit environment in mind. Browsers, however, are 32-bit (as far as JSOO is concerned). This MR adapts saturation_repr.ml to use Zarith's Z.t so that when compiled to JS, zarith's stubs get linked in and get us 64 bit emulation for integer arithmetic in the browser.

Note: one of the interpreter step invocation passes zero gas as the initial state. I don't know where this is coming from as of now. To workaround this, the gas costs of all instructions are temporarily made free.
