refactor(utils): update F1Field.e(res) function to remove the comparison checks with this._order #247

Closed aakansha1234 closed 7 months ago

F1Field.e(res) checks if it is >= this._order to determine if it needs to take a modulus with this._order. However, in v8 bigint implementation, this check is already present. So this check is not necessary as bigint implementation already does that. This commit removes these checks.

https://github.com/v8/v8/blob/497d8573dc80b1b69052a834bec894cf5d4238e7/src/builtins/builtins-bigint.tq#L380-L383

I was just reading zk-kit's F1Field code after studying modular arithmetic. Please let me know if this is useful!
