feat: integrating numscript rewrite

[ascandone]

Changelog:

• use the interpreter in https://github.com/formancehq/numscript under a feature flag
• run e2e tests with both versions

The history is a bit messed up after the last rebase I did but should mostly make sense so you can read commit by commit

Not a big deal but there is wrapper around time package in go-libs, which already round dates at microseconds (postgres precision)

and set UTC too

Approved but i would be grateful if you can change the decorating stuff around the parser.
Keep the option simple, and make the plumber in the module.go file.

Here the only diff is that I wrapped everything in this for loop

Not that here it's using the feature flag value

Same as before, here the only diff is wrapping all in a loop
