Allow using the crate with the latest/git version of screeps-game-api

[BlueskyFR]

This crate is currently incomptatible with the git version of screeps-game-api. How may I use with it?

[xilexio]

I changed the requirement from 0.21 to just 0. This is not the cleanest approach, but that particular interface has a relatively low chance of breaking anytime soon.

As for using it with the git version of screeps-game-api or even your own modified version of the API, you can fork this repo and specify git repo in dependencies. I did it like that

screeps-game-api = { git = "https://github.com/xilexio/screeps-game-api.git" }

in my fork of room_visual_ext that I use in my bot's Cargo file.
