Bumped pod spec to version `1.0.1`
Adding one to `intrinsicContentSize` is wrong.

The issue is that other libraries (e.g. `AutoLayoutCells`) calculate the height of table view cells by calling `systemLayoutSizeFittingSize` on the `contentView` of the cell. This *doesn't* take into account the separator height, which is 1 pt!
Instead, these consumer libraries need to be updated, *not* this library.
Bumped pod spec version to `2.0.0`.
