Separate "randomize treasure" and "randomize drops" flags

[tukkek]

Hello and thank you so much for this amazing project! I have been reading the source for randomizer.py and noticed that both DropObject and TreasureObject are assigned the t flag. Is there any reason why these couldn't be two separate flags?

So far I believe the ideal setup for me would be to randomize only shops and treasures - but not monster drops.

It seems like it should be a simple change but maybe there is a more complex underlying reason why these two features (random treasures and random drops) must always be used together?

Thanks again for the great project and sorry if I'm misreading some of this. I'm judging only by the source code and haven't ran any extensive tests to understand exactly how these work!
