Minimize Dependencies (i.e. disable default features or remove dependencies if possible)

[AS1100K]

Currently Cargo.toml is pretty good, it has few dependencies, but try to minimize them further

[dependencies]
bevy_app = "0.15"
bevy_ecs = "0.15"
flume = "0.11"
serenity = { version = "0.12", features = [
    "gateway",
    "framework",
    "model",
], optional = true }
paste = "1"
tracing = "0.1"
tokio = { version = "1", features = ["rt-multi-thread", "rt"] }
discord-sdk = { version = "0.4", optional = true }
async-trait = { version = "0.1", optional = true }

Also, paste is unmaintained, issue #2215 on advisory-db
