Long paths within file tree break compile

[Joeyrsp]

Describe the bug Running tweego on a folder with deeply nested children or a very long name results in an error and fails the process. Presumably related to the old windows max path length restriction of ~255.

To Reproduce

1. Take any working twee project folder.
2. Create a folder or set of folders with sufficiently long names (e.g. ./abcdefghijklkmnopqrstuvwxyz/abcdefghijklkmnopqrstuvwxyz/abcdefghijklkmnopqrstuvwxyz/abcdefghijklkmnopqrstuvwxyz/abcdefghijklkmnopqrstuvwxyz/abcdefghijklkmnopqrstuvwxyz/abcdefghijklkmnopqrstuvwxyz/abcdefghijklkmnopqrstuvwxyz/abcdefghijklkmnopqrstuvwxyz)
3. Run tweego (e.g. tweego -o "../index.html" .)
4. Receive error: warning: path .: CreateFile abcdefghijklkmnopqrstuvwxyz\abcdefghijklkmnopqrstuvwxyz\abcdefghijklkmnopqrstuvwxyz\abcdefghijklkmnopqrstuvwxyz\abcdefghijklkmnopqrstuvwxyz\abcdefghijklkmnopqrstuvwxyz\abcdefghijklkmnopqrstuvwxyz\abcdefghijklkmnopqrstuvwxyz: The system cannot find the path specified.

Expected behavior There should be no errors and it should succeed.
