Juan Cruz Viotti bf37ee72df Prevent selection of drives that are not large enough (#408)
* Make .selectImage() dialog return an object with a `path` property

This allows to return more than one value for the selected image,
like image size and other metadata for example.

* Return image size from .selectImage() dialog

This property will be useful to perform some sanity checks, like
ensuring the selected drive is large enough to contain the image.

* Store both the image path and the image size in the selection model

In order to simplify accessing such properties in an encapsulated
manner, `SelectionStateModel.getImage()` was replaced with the following
functions:

- `SelectionStateModel.getImagePath()`.
- `SelectionStateModel.getImageSize()`.

* Increase SelectionStateModel setter validation

The model not providing any kind of validation was the source of some
bugs I encountered while implementing the previous commits that would
not have happened otherwise.

* Prevent selection of drives that are not large enough

- The drive selector modal was modified such that drives that are not
large enough are crossed out, and the user is not able to click them.

- In the case of drive auto-selection, not large enough drives won't
attempt to get autoselected.

This commit introduces:

- The `SelectionStateModel.isDriveLargeEnough()` function.
