TINTO v1.2.1: Create images with PCA and t-SNE. Show feature positions

The "show_positions" parameter is added that, if activated when launching TINTO, shows the coordinates in the synthetic image of each of the characteristics

TINTO v1.2.0: Create images with PCA and t-SNE. Improve the blurring option.

In this version a filter is created since a matrix of size "2distancetotal_steps+1" is being created to act as a "filter", which covers the whole circular space of the minutiae determined by the distance and by the total number of steps.
This "filter", which is a matrix, would be multiplied with a scalar, which is the intensity value.
Finally, this resulting matrix is placed as a submatrix within the final matrix where the centre of the submatrix would be the position of the characteristic pixel.

• Blurring have been improved.
• Two new functions: createFilter and blurringFilter
• The distance now is in pixels (previously it was by percentage). By default is 2
• Sub-matrices have been created for blurring.
• Fixed the vertical and horizontal pixels bug.
