`plistutil` fails to convert NextSTEP and single-line plists to binary
First off, I want to thank you for this project and libimobiledevice in general. Time and time again I find myself using a library or tool from libimobiledevice and your hard work is greatly appreciated!
The issue:
Recently I added support for plistutil in an xml/plist->bplist wrapper script I was working on and noticed that it failed to convert a few of the files I threw at it during my testing.
The files that failed included: Swift.xspec (NextSTEP):
(

Localizable.strings (Also NextSTEP (?))
"Applications" = "Applications";
"System Applications" = "System Applications";
"User Applications" = "User Applications";
"Hidden Applications" = "Hidden Applications";
Vinyl.plist (Single-line format (?))
{ Filter = { Bundles = ( "com.apple.springboard" ); }; }
Note: I'm not 100% on the format classifications I gave to the files above.
The errors:
Swift.xspec: ERROR: Could not parse plist data (-3)
Localizable.strings: ERROR: Could not parse plist data (-3)
Vinyl.plist: ERROR: Failed to convert plist data (-1)
Upon running plistutil -i filename.extension -f bin -o filename.extension with plistutil version plistutil 2.2.0-88-g7d2cdc6-dirty on Linux (WSL).
This doesn't work because NextSTEP plist format is not supported by libplist. I am planning to add support for it (like I recently added JSON support) but I don't know when it will be finished.
Tested and confirmed working on all aforementioned test cases. You're the man, Nikias. Thanks so much for your continued work on this awesome project!
