v4 rewrite: All new design, core types, and stream-oriented interfaces (

#302)

* Initial commit of v4 rewrite; core types, methods

* Correct file permissions

* Use xz lib with standard license (close #259)

* zip: Decode non-UTF-8 encoded filenames (by @zxdvd)

Closes #147
Supersedes #149

* Improve ArchiveFS; fix directory traversal

* Add placeholder command for now

Not sure when I'll get around to reimplementing this for v4.

* ci: Require Go 1.17

* Swap params for Inserter interface

More aesthetically pleasing when enumerating files

* Add readme
