#11 maximum zoom level in visca_cli.c

[Zuba]

Thank you for developing the library. I'm using it for Sony block camera (FCB-EX780) and it works well!
Just one minor bug in visca_cli.c:
in line 3439 ("set_zoom_value"), the software only allows the argument be under 1024 but the actual camera supports it up to 18000. You may remove the whole (intarg1 > 1023) part?

Thanks!!
