I've fixed the _boxed formatting to strip ANSI codes when calculating string lengths (so you can use ANSI colours properly)

changed the colours for the "failed systems" warning so it's absolutely obvious

wrapped the JSON ensemble output in a write_ensemble() function which automatically gzips or bzips depending on the filename extension (or this can be explictly set in grid_options['compress_ensemble'] ).

implemented binary_grid-style statistics over last n_logging_stats verbose outputs (50 by default)

added ANSI colour to output if in a terminal (i.e. with a tty)

fixed the cmd-line parser to work in the form x=y as intended (downside: no help output, but that just said how to use the old parser which doesn't exist now)

tried to run this from surrey pc, got the following error: /usr/bin/ld: /tmp/ccca3KKm.o: relocation R_X86_64_32 against .rodata.str1.1 can not be used when making a shared object; recompile with -fPIC /tmp/ccca3KKm.o: error adding symbols: Bad value collect2: error: ld returned 1 exit status
