Using the .xz would be better. Pretty sure Python supports it? |

We only generate manifest.json.xz on custom build server today. I would be happy to change it to xz after we do the firmware server side of changes to serve the xz format. |
Fetch the xz-compressed manifest from firmware.ardupilot.org and decompress before writing the on-disk cache. Keep If-None-Match and If-Modified-Since revalidation unchanged.
Switch the default CBS manifest source from the 67 MB JSON file to the 0.7 MB xz file on firmware.ardupilot.org.
Add ManifestClient tests for xz decompression and conditional cache hits. Assert the default manifest URL ends with .xz.

Thanks to @peterbarker we do emit xz on firmware server now. I have changed the PR to use the xz manifest. |

#244 added support to use manifest.json for listing versions on custom build server.
This PR does an enhancement to use the compressed manifest.json instead of downloading the whole big file.
PS.: I somehow was under an impression that we currently do not host gz manifest in firmware server and we need to make the change there first before we start using it here, but looks like we already do. @peterbarker
