added gcc args for debugging (valgrind, gdb, etc.)

more attempts to clean up timesteps: now check the minimum timestep by default, and have separate macros for when we don't want to

also fixed bug where nucsyn checkfuncs weren't wrapper with NUCSYN

fix issue where the timestep wasn't being limited in a system with only massless remnants when fixed_timesteps should be triggered

fixed issue where the code got in an infinite loop after the above failure

fix TPAGB issue where massive cores were checked vs MCh just before the TPAGB: we now explicitly check that the star is a TPAGB star to do this

updates to meson.build: moved the cflags around a bit to make sure the numerics flags are in the required rather than optional list

sync latest perl mods (binary_grid::C path fix)

you can now set the arrows in the log with the UPARROW and DOWNARROW environment variables

add colour%d option to allow the user to override the ANSI colours

Added Tout and Pringle 1992 magnetic wind loss with multiplier option (default is 0.0, so this wind is off)

now propagate vb flag through nuclear-burning routines

change to stellar structure to only allow thermal pulses if Mc < MCh: this *might* help mint post-CHeB (although the timescales are still all messed up!)

updated CHeB loading logic

add ability to use test_data/whatever if data/whatever is not available, this is activated by MINT_fallback_to_test_data

add ability to load CHeB data tables

add function to detect when we're on the post-AGB

updated the Foreach_string macro to be more like other loops, i.e. the char* string is declared automatically.

updated some of the algorithm lists to include their description strings, and use these appropriately

updated the qcrit macros so they are available for general stellar types (not just GB) and are handled better as cmd-line macros

checked over the logic in the evolution splitting and how it handles the pre_event stardata struct: this seems to be ok

added (optional) checkfuncs for the nucsyn cycles so they are not called unless the temperature and density are in suitable ranges.

add preference evolution_splitting_sn_eccentricity_threshold to set the eccentricity above which evolution splitting should happen

add binary_c_mutex struct type: this contains a Boolean to make sure we cannot free a mutex twice. Added also Pthread* macros and primitives to allow one set of macros for pthread lock/unlocking.

add pthread warnings

updated docs

renamed pthread mutexes to an array, with definitions in binary_c_mutexes.def
This makes it easier to init and destroy the mutexes when the store is built and freed.

new "binary_c_install" option which, currently, is the same as "binary_c_install_legacy" but is less typing.

updated docs to include the above change and -Dvalgrind=true
