Is it necessary to have this as a method?

I like the idea of having TissueMask that is flexible and does the right thing based on the input
@ernestoarbitrio thoughts?

This was already addressed in the past in #360, but 10px of border thickness is not enough for some use cases

Description
This PR fixes the calculation of the tissue mask (and related usages) in case we have a tile completely covered with tissue.
From #357 "Sometimes the filters used to extract the tissue mask of the tile are not identifying the whole tissue, but the cell nuclei only. Therefore during tile extraction from the WSI, the tile will be wrongly discarded as if it contained too much background."
In order to solve this, the filters are applied on the tile with a white border of 10px, and then the border is removed from the returned mask.
