This happens from tar files being created in their target directory, apparently.
Avoid infinite walk. Fix #383.

* Cleaning up directories containing dots

* Cleaning up some debug bits

* More descriptive tests

* Update fs.go

Updating per suggestion, looks great!

Using path.Base() doesn't parse correctly for WIndows filepaths.
Use filepath.Base() instead.

* demo bug

* check 2 bytes of zlib header

* add .zz test

* Option to use number for user and/or group names

* add NumericUid and NumericGid to Tar struct
* writeFileToArchive: set Uname and Gname to empty string if NumericUid and NumericGid are true, respectively.

* Join options to use numeric user and group id

* join NumericUid and NumericGid in Tar struct
* name the new option NumericUidGid

* Apply suggestions from code review

I don't like this solution, but it's all I could think of while
preserving the API.
Anyone using CompressedArchive to Extract files without using archiver.FS
will need to figure it out on their own
if they don't close files before the call to Extract returns.

* Fix create archive to a continuous writing source file failed

fix: fix iteration bug

Close #397

Also minor tweaks

* Add lzip support

* Make the extension comparison to strict

I think this is what @WeidiDeng intended from #354

…led (#419)

This reverts commit a902fcc.

* WIP

* More WIP

* Finish improvements (probably)

Split Archival into Archival/Extraction since some archive formats can't do both. Rar is proprietary for creating, and there's no pure-Go 7z writing implementation that I know of.

- Extractor no longer requires a filename filter (kind of pointless at best, confusing at worst)
- CompressedArchive renamed to Archive
- Archival is now just creating archives
- New Extraction interface is for reading archives
- Archive format can compose compression, archival, and extraction
