Implement Experiments

[kozabrada123]

Implement / parse guild and user experiments, specifically in the ready payload

See:

    /// User experiment rollouts for the user
    ///
    /// TODO: Make User Experiments into own struct
    // Note: this is a pain to parse! We need a way to parse arrays into structs via the index of
    // their feilds
    //
    // ex: [4130837190, 0, 10, -1, 0, 1932, 0, 0]
    // needs to be parsed into a struct with fields corresponding to the first, second.. value in
    // the array
    pub experiments: Vec<serde_json::value::Value>,

A custom serde Deserialize implementation is likely needed
