Update @andrewbranch/untar.js

[andrewbranch]

Fixes #101

andrewbranch/untar.js@095c173

Info source:

The name field (100 chars) an inserted slash ('/') and the prefix field (155 chars) produce the pathname of the file. When recreating the original filename, name and prefix are concatenated, using a slash character in the middle. If a pathname does not fit in the space provided or may not be split at a slash character so that the parts will fit into 100 + 155 chars, the file may not be archived. Linknames longer than 100 chars may not be archived too.
