www/hs-wai-extra: Update to 3.1.14

3.1.15
    Request parsing throws an exception rather than erroring #964:
        Add RequestParseException type and expose it from the Network.Wai.Parse \ 
module.
        Behavior change : parseRequestBody and parseRequestBodyEx (exported from \ 
Network.Wai.Parse) throw RequestParseException rather than calling error.

3.1.14.0
    defaultGzipSettings now exported to not depend on Data.Default #959
