Reference draw ZIP archives contain __MACOSX metadata files

The 11 reference draw archives added in posteriordb v1.1.0 contain an extra AppleDouble metadata entry under __MACOSX. These seem to have been unintentionally added (#155 removed earlier entries).

Could these 11 archives be recreated without the __MACOSX entries? Perhaps it would be useful to add a validation check preventing macOS metadata from being included in future archives?
