* tags instead of temp
* Merge in master, adapt to changes in the MappingsReader, delete unused ToolBreakSpeedsUtils class
* oops
* clean diff
* Change namespace from `geyser_custom` to just `geyser`
* Don't force a namespace at all; just like blocks don't
* Tags for items are now, as blocks, NonNull. Additionally, calling the .tags() builder multiple times will not add both sets of tags, but replace the existing tag set
* Remove @NotNull usage in favor of @NonNull
* Allow setting null for tags, but ensure that .tags() is always non-null
* Fix nullable annotation on tags method in the builder interface
