By default, Python outputs spaces after commas and colons when dumping JSON
data. This is normally fine, but when exporting large amounts of JSON (such as
cache info) it is more space efficient to export JSON without whitespaces. To
do this, simply pass `separators=(",", ":")` to `json.dumps()`.
Although the space savings aren't massive, they do reduce the size of the cache
folder by a couple of megabytes:
| Method | Size |
|---------|--------|
| Current | 31.2MB |
| This PR | 29.3MB |
For comparison, the size of the cache folder with the `--sqlite-cache` option
is about 27.5MB.
