XhrLoadStrategy.setExtensionXhrType('mp3', XhrResponseType.Buffer)

如果资源URL中没有有效后缀(通过resource-loader的getExtension方法获得)，会导致默认使用text格式，而非arraybuffer返回，加载音频报错

if there isn't a valid extension within the resource URL (returned by getExtension function of third-party resource-loader module), it will load using text by default, instead of arraybuffer, and there we are getting an error

Failed to execute 'decodeAudioData' on 'BaseAudioContext': parameter 1 is not of type 'ArrayBuffer'.

建议如果设置资源type字段为audio，强制使用arraybuffer

i suggest if user sets the resource's type field to audio, use arraybuffer to parse fetched data rather than let the third-party module determine by itself (code)
