Feature Request: Adding "OR" functionality for structures

[rithik25]

Currently, there is only "AND" functionality that is natively implemented when searching for structures. For example, you can search for a seed that has a mansion AND a village. It would be really helpful to have an "OR" functionality as well so that you can search for seeds that have a mansion OR a village.

Being able to combine AND and ORs would be nice as well. For example, having the functionality to search for seeds that have a mansion AND a village OR a mansion AND a pillager outpost.
