Feature request: Assert less/greater than or equal to

I was surprised that this doesn’t exist already.

assert.lte(3, 3, '3 is less than or equal to 3');

It might seem like a small shortcut, but things get messy when you’re expecting a number and don’t get one:

console.log(null <= 4);  //=> true
console.log(undefined <= 4);  //=> false

I currently do something along the lines of:

const lte = actual === max || actual && actual < max;
assert.isTrue(lte, '...');

… but this still isn’t perfect, especially if you want '3' < 4 to be an error (comparing a string and a number).

I propose that lte/gte be designed to work strictly with numbers and throw for anything else.

Just discovered that expect / should has this.

expect(3).to.be.at.least(3);
expect(3).to.be.at.most(3);

It would be nice in the docs to include greater/less than so that when searching least and most will pop up
