What is the current behavior?

no function to range check.

Resolves #16

What is the new behavior?

Added a function RANGE_CHECK which takes num: bigint as an input and checks the range of the num. If the num < 2^128, it will throw an error, or else return num.

also: removed a console.log() which was slipped in and was not cleaned up.

I forgot to ask but should I keep the RC_BOUND const in the builtins.ts file or should I put that in constants.ts.

I felt the constant is only valid for range_check builtin so I put in builtins.ts, but lemme know if I should have put that in constants.ts.

Shit I think I made an oops with rebasing ;-;
Lemme know if this will create any problem. I will branch through latest main again, and create a PR exactly same as this.
