No Spiders

• Fixed spawn eggs broken in 1.21.4.

• Fixed a crash in version 1.21.3 which occurs when you become a ""spider"" in spectator mode.

/shader/posts -> /post_effect

Minor update: no visible changes.

• Update to 1.21: pack_format updated.
• Add "supported_formats".

• Update to 1.20.4: pack_format updated.
• Post-processing shader of Spider spectator view removed. (As a spectator, when you enter a ""Spider"", you no longer have the quintuple vision visual effect).

First version.
