Just an FYI - RAR support is currently unavailable for PHP7.0 (not a bug)

Figured I'd post this for anybody trying to get RAR to work with PHP7.0 and Codiad-Archives:

[email protected]:

Rar hasn't been updated since 2013 - thus the PHP/Zend APIs aren't updated and likely won't compile against 7.0. [...] I've assigned this to cataphract as they're the author of the PECL extension. I'll email and see if they're available to update to PHP 7. If not, I'll take a look at it.

See this bug report for more details: PHP Bug #71399: Package: rar (PECL): Can't compile when using PHP7.0.

@rafasashi you might want to update your README.md to reflect this in the meantime.
