When I try to get the url that links to sfm_cluster, it returns to me a binary stream. After that , I write it content into a txt file,\r\nbut it becomes messy code. Is there any way to decode the messy code or api that I can get the *.ply format file?\r\nThank you!\r\n\r\n**Additional context**\r\n![image](https://user-images.githubusercontent.com/54012035/189475049-20e77c84-1614-411d-93e8-fd549e21b1ef.png)\r\n\r\n![image](https://user-images.githubusercontent.com/54012035/189475058-fbcdf5c6-ebc5-42c4-8c3f-628ee8e524c7.png)\r\n\r\n\r\n\r\n","author":{"url":"https://github.com/neverland-haha","@type":"Person","name":"neverland-haha"},"datePublished":"2022-09-10T08:13:06.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":11},"url":"https://github.com/147/mapillary-python-sdk/issues/147"}
