PF2e Line Template Fix

The module corrects the foundry beam pattern to match the line examples from the pf2e rules. When the pattern is drawn from a corner, additional cells are often coloured in. In other situations, even when the aforementioned problem does not occur, the wrong squares are often coloured in compared to the examples. The correction is achieved by applying the Bresenham’s line algorithm. As a result, 5-foot rays begin to trace precise lines. It has been tested and confirmed to work only with 5-foot rays.
