A font that uses only TWO rows of unicode blocks!

This PR Adds the Double-Blocky Font! Based in the font "Blocks in two lines" from https://texteditor.com/multiline-text-art/ and the second font from https://fsymbols.com/generators/tarty/. Double blocky contains much more characters than both, some modified and original ones (like M, W, I, l, z), uppercase/lowercase differentiation and all punctuation signs. it was made by using https://textpaint.com and https://patorjk.com/figlet-editor/#/edit
