"pack" fails on Windows when ran on ImDisk ramdisks

[smx-smx]

xdvdfs pack faults when operating on ramdisks created with ImDisk toolkit:

> xdvdfs pack R:\files R:\output.iso
`error: Incorrect function. (os error 1)`

Repro steps:

• Create a ramdisk using https://sourceforge.net/projects/imdisk-toolkit/
• Put some files there
• xdvdfs pack R:\files R:\output.iso

Tested on commit 1cc850b

In general this should be a bug with the filesystem; based on what I could find this error would imply it doesn't implement the particular operation we use for path canonicalization.

That being said, we can probably work around it with some tradeoffs in detecting output path validity, see if this works for you: #104

Thanks for the quick reply.
I tried the patch and i confirm it works now.
