entity_effect : rename hideParticles to flags

[Robbilie]

In reference to: https://github.com/PrismarineJS/node-minecraft-protocol/issues/951

Would it be possible to rename the hideParticles field to flags like in the protocol definitions? https://wiki.vg/Protocol#Entity_Effect

hideParticles is a bit missleading and doesnt represent the two other values behind the flags

        "packet_entity_effect": [
          "container",
          [
            {
              "name": "entityId",
              "type": "varint"
            },
            {
              "name": "effectId",
              "type": "i8"
            },
            {
              "name": "amplifier",
              "type": "i8"
            },
            {
              "name": "duration",
              "type": "varint"
            },
            {
              "name": "hideParticles",
              "type": "i8"
            }
          ]
        ]
