[enhancement] An additional option to disable beds setting spawn

[ShinyArmorYT]

While there are plenty of mods that can disable both sleeping and setting your spawn with beds, the only one (to my knowledge) that lets you only disable setting your spawn with them but keep sleeping is MiscTweaks_, which comes bundled with a lot of other potentially useless functionality. This option would be particularly useful in hardcore packs using Somnia Refreshed.
