somewhat related to #12

After TinyGo supports WASI, we could use https://github.com/vugu/vjson

func (ctx context) OnVMStart(vmConfigurationSize int) bool {
    data, err := proxywasm.HostCallGetVMConfiguration(vmConfigurationSize)
    if err != nil {
        proxywasm.LogCritical("error reading vm configuration", err.Error())
    }

    var c map[string]interface{}
    if err := vjson.Unmarshal(data, &c); err != nil {
        panic(err)
    }

    proxywasm.LogInfo("vm config: \n", c["name"].(string))
    return true
}

verified that it works with WASI target:
