Override armor materials for palettes

[HEROshineMC]

Vanilla has an optional override_armor_materials field in trim material definitions, which lets you pick an alternate palette on an armor material. This is useful for making a darker/lighter version of a palette to display on the same armor material, for contrast. Vanilla uses this for the trim materials that are also armor materials, so diamond can have a darker diamond palette for example. Would you consider adding something like this to Simple Trims? The problem with the vanilla field is that it's hardcoded to only work with vanilla armor materials, like diamond, gold, etc.

So adding this to Simple Trims would be very useful for mod developers like me to utilize. It'd also be useful for developers adding an armor material that happens to also be a trim material in vanilla, like amethyst armor, so they can make it use a darker palette like the rest of the vanilla armor materials that are also trim materials.

sounds like an interesting idea :) i haven't done any modding for a while so maybe this will get me back into it and sort this mods code a bit.
