implement optional text justification (justify=['left', 'right']) in KicadModTree Text Node
This merge request implements optional justification ('left', 'right', or None) to the KicadModTree Text node.
Example:
kicad_mod.append(Text(type='user', text='some text', at=[x, y], layer='Cmts.User', size=[fontsize, fontsize], justify='left')) # or 'right' or None (default)
Used in !809 (merged) (for proper alignment of text and graphics on the User.Comments layer).
