Homebrew JWTDecoder doesn't check integrity of JWT

[jonigkeit]

https://github.com/trifork/TIM-iOS/blob/main/Sources/TIM/Helpers/JWTDecoder.swift#L4-L7

static func decode(jwtToken jwt: String) -> [String: Any] {
        let segments = jwt.components(separatedBy: ".")
        return segments.count > 2 ? decodeJWTPart(segments[1]) : [:]
}

Does not check the integrity of the JWT.
