Go Down ! [FABRIC]
Allows on-demand crawling with the (by default) "Z" key. It is configurable in the options, movement section, under label "Crawl".
Crawling forces the player in swimming pose similarly to suffocation prevention. It makes the player small enough to crawl through small (< 1 block) spaces.
Requires Fabric API.
Needs to be on the client as well as the server.

Inspired by the no longer maintained Crawl mod by Fewizz (https://www.curseforge.com/minecraft/mc-mods/crawl), later updated by Chocohead and McSkinnerOG (https://github.com/FabricCommunity-Old/Crawl). This mod used a custom pose, different from the vanilla swimming one that Go Down uses.
