Allow segments to auto-expand LoROM to size #389
Description
Asar has the (in my opinion) undesirable behaviour where it does not auto "expand" a new rom being built from scratch while in lorom mode. (This works fine for hirom mode.) After filling the first $8000 bytes, further segments no longer work because the ROM has "no more freespace". This can be worked around with an org command (e.g. org $81FFFF : db $FF) but this requires beforehand knowledge of the size of the ROM to be built, which is not ideal.

lorom actually does have autoexpand, you just need to start with a rom of at least 512KB. this is because the lorom autoexpand mechanic is somewhat tailored to smw hacking. i added hirom autoexpand at selicre's request, and since there's no reason to have any specific lower bound there i just made it start from 0.
i guess i could just change lorom to also start at zero?
