[Suggestion] Crawl mode client and server side

[juke31123]

Describe the feature

I suggest a feature which exploits the behaviour seen in the link video. https://youtu.be/fTd6kTMLkuQ?si=DJW3g52EHWHBwg1m

The things which would be archive able with this module:

• Clientside crawl: you would be able to get stuck on blocks and dont move.
• Server side Crawl: while in client side crawl you would be able with specific movement to turn the Clientside crawl in to server side crawl. (how it would work is explained in the video)

Side note: because we use Meteor we would be able to just force Client side crawl which mean we could just walk up to one block high tunnels and enter without any items.

Before submitting a suggestion

• This feature doesn't already exist in the client. (I have checked every module and their settings on the latest dev build)

• This wasn't already suggested. (I have searched suggestions on GitHub and read the FAQ)
