Feature request: Support ManifestFilesMixin

[WhyNotHugo]

I'm using S3 with ManifestFilesMixin (it doesn't make sense to use S3 for staticfiles without it since invalidation becomes extremely complex and costly).:

from django.contrib.staticfiles.storage import ManifestFilesMixin
from storages.backends.s3boto3 import S3Boto3Storage


class MyStaticStorage(ManifestFilesMixin, S3Boto3Storage):
    """Storage that uses S3 and hashes in filenames to avoid caching issues."""

However, collectfast does not properly collect staticfiles. The manifest is missing, and no files are correctly copied onto the storage / bucket. There's no error though, and lots of processing is done for 2:45m.

I'm guessing that collectfast makes some [wrong] assumptions regarding the underlying setup, but I can't quite follow what that might be.

I'll review PRs implementing this.

I'm not quite sure where the bug is though, so don't think I'll be able to push a PR.

BTW: why is this labeled "feature request"? It's an actual bug -- the code makes an assumption about how files are stored that's not true for all use cases.

Because ManifestFilesMixin was not around when collectfast was first built and support for it has never been implemented. Since integration with ManifestFilesMixin has never been supported there can't be bugs in the integration.
