Function rotateArray2DMajor

rotateArray2DMajor<T>(
arr2d: Array2DRowMajor<T>,
amount: number,
): Array2DRowMajor<T>
mutate and rotate the major-axis of a 2D array by the specified amount to the right.

given a row-major 2D array arr2d, this function would rotate its rows by the specified amount. a positive amount would rotate the rows to the right, and a negative amount would rotate it to the left.
Type Parameters
- T
Parameters
- arr2d: Array2DRowMajor<T>
  the 2D array to be rotated.
- amount: number
  The number of indexes to rotate the major-axis to the right. positive values rotate right, while negative values rotate left.
Returns Array2DRowMajor<T>
The original array is returned back after the rotation.
Example
```
import { assertEquals } from "jsr:@std/assert"

const arr2d: Array2DRowMajor<number> = [
	[1 , 2 , 3 ],
	[4 , 5 , 6 ],
	[7 , 8 , 9 ],
	[10, 11, 12],
	[13, 14, 15],
]
rotateArray2DMajor(arr2d, 2)
assertEquals(arr2d, [
	[10, 11, 12],
	[13, 14, 15],
	[1 , 2 , 3 ],
	[4 , 5 , 6 ],
	[7 , 8 , 9 ],
])
