[feature request] Create default filter options

[RandomGgames]

By default, when opening a new world and opening the filter option, the default option is "xPos <= 100 AND xPos >= -100 AND zPos <= 100 AND zPos >= -100".

Being able to set a custom one to open with or save presets for this from the settings menu would make repeated chunk deleting for example much easier to do!

It would also then be nice to have a filter that filters all non-natural/non-generating blocks to allow for better chunk resetting
