[Feature Request] Helper to get available position

[fabiot21]

Add an utility or helper class that can return an available position within the grid given a new potential item (only w and h) and current items. This helper could provide the x and y coordinates where the new item can be placed within the items.

The function could be based on getAvailablePosition

[fabiot21]

(this class could be extended to have more utility functions)

Maybe something like this

<Grid {...} let:controller={gridController} />

gridController.getAvailablePosition()
gridController.somethingUseful()

[fabiot21]

what about bind:controller={gridController} or import { gridController } from '$lib'? to have a reference outside the Grid component
