Bootiso writes to incorrect folder when using wimlib-imagex

[Ill1]

Wimlib-imagex searches for the first dot and puts a number behind it to generate successive image splits.
The bootiso scripts generates mount points with dots in the folder names.
This causes the script to fail when using wimlib-imagex because it tries to write the second, third and fourth... files to the wrong temporary folder (mount points).

@Ill1 Thanks for your feedback.
I have successfully used and tested the wimsplit feature with wimlib 1.13.0, before releasing.

Can you give me your system information (neofetch) + wimlib version to help investigate this issue.

Also, it would be nice of you to use a title which express the issue you encountered instead of the suggested solution, so that I can mark it as bug.

@jsamr Sure:
wimlib-imagex (distributed with wimlib 1.12.0)

Apologies for including the how-to-fix rather than what-was-broken - The fix worked for me on local, I initially tried to setup a Pull Request with the same.

@Ill1 OK. You are describing a wimlib bug, corrected in 1.13, which has a nasty side effect on bootiso!
From their changelog:

wimsplit (API: wimlib_split()) now correctly handles a dot in the path to the first split WIM part, prior to the filename extension.

So I'll publish a patch to have retro-compatibility with earlier versions of wimsplit.

Thanks @jsamr

@Ill1 I'll keep it open until released for others stumbling on this :-)

Should be fixed in v3.3.0, let me know!
