Allow cc65 ethernet drivers to be loaded statically instead of dynamically. This saved quite some space in scenarios without additional cc65 drivers to be loaded for i.e. a mouse because in those scenarios the cc65 module loader isn't necessary. And without the module loader typically the cc65 heap manager isn't necessary.
