pkgres:

* pyz: yeet the resource tar which is now pointless thanks to pkgres
* cache impresource stuff because pyz lookups are Extremely slow
* prefer tx_file when possible for slightly better performance
* use hardcoded list of expected resources instead of dynamic
   discovery at runtime; much simpler and probably safer
* fix some forgotten resources (copying.txt, insecure.pem)
* fix loading jinja templates on windows
