Assignment and conversions, following decball. Strings in the output format of deccball_get_str and expressions such as "[1 + 2*I +/- 0.01]", "[1 + 2*I +/- (0.01 + 0.02*I)]" or "([1 +/- 0.1] + [2 +/- 0.2]*I) / (3 - I)" are accepted, also inside strings for polynomials and matrices over complex balls.
