Increased the maximum number of modules that can be inserted and module icons overflow from the beacon when using “alt mode”.
Made a local modification to increase the default 2-width icon display to 5-width,
but it cannot be distributed because it cannot be made into a lua statement.
I believe the maximum is 25 icons, as there seems to be no limit on top and bottom widths in “Factorito's lua”.

Default:
{inventory_index = defines.inventory.beacon_modules, shift = {0, 0}, multi_row_initial_height_modifier = -0.3, max_icons_per_row = 2}.

FIXES:
{inventory_index = defines.inventory.beacon_modules, shift = {0, -0.8}, multi_row_initial_height_modifier = -0.3, max_icons_per_row = 5}

Translated with DeepL.com (free version)

I am already working on something kind of similar to this but scaling with the amount of max. modules that are set in the settings :)

(Prototype is already in the data-final-fixes.lua but commented out if you are curious how I want to implement it ^^ )
