- updated to 0.22

Documented:

- Issue tracker is now github

Changed:

- Skips tee and leak tests for closed STDIN on Perl prior to
5.12 when PERL_UNICODE=D. Documented lack of support as
a known issue.

- Isolated tee subprocesses from effects of PERL_UNICODE as a
precaution (though this did not fix the above issue).

- Improved layer detection for handles proxied due to being closed
or tied.

Fixed:

- Nested merged captures that include an external program call no longer
leak STDERR to the outer scope [rt.cpan.org #79376]

- Work around rt.perl.org #114404 by forcing PerlIO layers back on
original handles [rt.cpan.org #78819]
