Add moveIndex

[cjquines]

Equivalent to move from Ramda; the most requested function in Lodash.

The one-liner R.moveIndex(data, from, to) would be data.toSpliced(from, 1).toSpliced(to, 0, data[from]), but this would also have R.moveIndex.strict, like R.swapIndices.strict, which is another reason to have this function in Remeda proper.

I'm cool with a moveItem function.

but this would also have R.moveIndex.strict, like R.swapIndices.strict, which is another reason to have this function in Remeda proper.

I couldn't find a swapIndices.strict in Remeda, what did you mean by this?

[cjquines]

oops, i thought we had a swapIndices.strict. i was referring to the fact that swapIndices was typed for tuples:

expectTypeOf(swapIndices([2, 'a'], 0, 1)).toEqualTypeOf<[string, number]>();

a hypothetical moveItem should also be like this:

expectTypeOf(moveItem([2, 'a'], 0, 1)).toEqualTypeOf<[string, number]>();

Yea, it should provide good typing for tuples
