[Feature Request] Save Preferred Default settings

[Avasam]

@homothetyhk @flibber-hk I would like to be able to save my preferred rando settings to be used as defaults whenever starting a new game.

@Avasam HK modding is moving over to HK version 1.5.x.x, and randomizer should be ported after not too long (hopefully). The option to save and load custom settings presets will be included in the first release.

I'll add that because of how the save data in rando 3 has been implemented, this functionality would have been quite a hassle to include there (which is why it hasn't been included earlier).
