Implements various testing utils.

You can import these APIs from the testing package. For example:

from std.testing import assert_true

def main() raises:
    x = 1
    y = 2
    try:
        assert_true(x==1)
        assert_true(y==2)
        assert_true((x+y)==3)
        print("All assertions succeeded")
    except e:
        print("At least one assertion failed:")
        print(e)
