* add xz to std.compress * prefer importing std.zig by file name, to reduce reliance on the standard library being a special case. * extract some types from inside generic functions. These types are the same regardless of the generic parameters. * expose some more types in the std.compress.xz namespace. * rename xz.stream to xz.decompress * rename check.Kind to Check * use std.leb for LEB instead of a redundant implementation
