feat: add random integer generation operation

[cktgh]

Currently there is NO easy/accurate way to generate random values of a specific range.
The existing "Pseudo-Random Number Generator" allows generation of bytes only, and processing that result into values of a specific range is difficult (see attempt at #1954).

This pull request adds "Pseudo-Random Integer Generator", an operation for generating random integers of a user defined range.

• Accurate outputs with no "modulo bias", by using the "rejection sample" method.
• Support values ranging from Number.MIN_SAFE_INTEGER to Number.MAX_SAFE_INTEGER.
• Support generating multiple values at a time with a delimiter option.
• Uses Crypto.getRandomValues() under the hood for cryptographic security. This is also consistent with the existing "Pseudo-Random Number Generator".

Design Notes

• Avoided the use of BigInt during random bytes generation for performance. This implementation stitches 32 bit integer values together under the hood.
• Did not change the existing "Pseudo-Random Number Generator" at all.
  • Separate from "Pseudo-Random Number Generator" to avoid dealing with compatibility issues for the existing recipes.
  • I think its best to add a "mode" option under "Pseudo-Random Number Generator", and in theory we could just add the new arguments at the back. I actually did that at first and it looked really ugly so I separated it into this new operation instead.
• Tests are not added because its not really necessary, and besides "Pseudo-Random Number Generator" doesn't have tests neither. 🤷‍♂️
