Support for indexed tar.xz file from pixz tool

[0bi-w6n-K3nobi]

I already tested several fuse tool, including infamous archivemount, for compressed files. I have a lot of log file into 7zformat. At last, I did try the good one pixz and lzofs fuse tool counterparty. It's a great, but did not access tar in transparent way.

For solid compressed 7z file, I know that fuse-archive will be indexing before that mount it, and I need wait for that. But, for pixz tar file it's not necessary because that already had internal index.

So, Is it possible implement to use pixz internal index for mount?

Note: The code for indexing and access it can founded at common.c and write.c files at GitHub. The functions are called *_file_index_*.

Since fuse-archive is built on top of libarchive, this feature request might be a feature request for libarchive.

By default, fuse-archive now works in fully cached mode. See documentation. I don't think there is a need to use a third-party tool in order to scan and index a tar.xz archive.
