easier way to get red sand

Red sand is a pure decoration bloc, so it would not be overpowered to make it renewable&easier to get, for it's very hard to obtain.

I think that it will be a good idea to demande to players to go in badlands biomes to get redsand, and this should not change. Perhaps, it would be good to make normal sand turn iron redsand if it is place on a badlands biome, unless there are water near it, like the coral mechanic (but this is only a simple example).

Thank you for reading.
