Bug in reading L2-phases from GRAS raw sampling files

Description
There's a bug in ropp_pp_grasrs2ropp which causes an erroneous interpretation of the L2 phase data.
Lines 319 - 320:
319 cl_exphase_p2(:) = cl_exphase_l2_nco(:) - & 320 (c_light/(2.0_wp*pi*f_L2))*cl_phase_l2_iq(:)
Minus should be a plus. Like this:
319 cl_exphase_p2(:) = cl_exphase_l2_nco(:) + & 320 (c_light/(2.0_wp*pi*f_L2))*cl_phase_l2_iq(:)

Safe to include in ROPP6.1? Let's try it.

No - it'll mess up the test folder (IT-PP-05). Send it back to 7.0.

For the ropp_pp_grasrs_test.nc example GRAS RS data provided with the ROPP test data sampling, this changes the L2 excess phase by ~1m where it is > 500m. It makes a large fractional difference where the excess phase is small, however:
