We now use the golang error wrapping format specifier `%w` instead of the
deprecated github.com/pkg/errors package.

if the layer cache doesn't already exist, automatically create it from
the layer TOC.

automatically detect holes in sparse files (the threshold is hardcoded
at 1kb for now) and add this information to the manifest file.
The receiver will create a hole (using unix.Seek and unix.Ftruncate)
instead of writing the actual zeros.

avoid parsing each json TOC file for the layers in the local storage,
but attempt to create a lookaside cache in a custom format faster to
load (and potentially be mmap'able).
The same cache is used to lookup files, chunks and candidates for
deduplication with hard links.
There are 3 kind of digests stored:
- digest(file.payload))
- digest(digest(file.payload) + file.UID + file.GID + file.mode + file.xattrs)
- digest(i) for each i in chunks(file payload)

try to reuse an existing cache object, instead of creating it for
every layer.
Set a time limit on how long it can be reused so to clean up stale
references.
