MAXICODE: add minimal encoding by Bue Jensen (BWIPP PR #279),
around 20% slower than current but much better; numerous other fiddlings reedsol: reverse result in `rs_*encode*()` routines & adjust clients appropriately (may replace later with something faster) test suite: cater for MAXICODE SCM better; add assert & dataset totals BWIPP: update to latest gen_gs1_lint.php: restrict line length to 118 for func calls
