Subject: [PATCH] JXR: jxrlib cannot write HDP and WDP formats

According with JXRLib GetIIDInfo(), HDP and WPD formats are read only.
```
    static PKIIDInfo iidInfo[] = {
        {".jxr", &IID_PKImageWmpEncode, &IID_PKImageWmpDecode},
        {".wdp", &IID_PKImageUnsupported, &IID_PKImageWmpDecode},
        {".hdp", &IID_PKImageUnsupported, &IID_PKImageWmpDecode},
    };
```
