Support constructing array from JSON

Nobody has claimed this yet.

Example:
```ts
import { array, equals } from 'vectorious';

const x = array([1, 2, 3]);
/*
array([ 1, 2, 3 ], dtype=float64)
*/

const serialized = JSON.stringify(x);
/*
'{"data":{"0":1,"1":2,"2":3},"dtype":"float64","length":3,"shape":[3],"strides":[1]}'
*/

const deserialized = JSON.parse(serialized);
/*
{
data: { '0': 1, '1': 2, '2': 3 },
dtype: 'float64',
length: 3,
shape: [ 3 ],
strides: [ 1 ]
}
*/

const y = array(deserialized)

assert(equals(x, y));
```

Start with the TypeScript implementation of the array constructor and the JSON example in this issue. Determine how the deserialized object should be accepted while preserving data, dtype, length, shape, and strides, then verify that equals(x, y) succeeds for the shown example.
