[bug] `wl-screenrec` thread panic

[sand4rt]

I ran cargo install wl-screenrec and then wl-screenrec on fedora/hyprland and got:

thread 'main' panicked at wl-screenrec-0.1.7/src/cap_wlr_screencopy.rs:99:18:
called `Option::unwrap()` on a `None` value
stack backtrace:

could you try latest git? i've improved the error message to hopefully give me more context.

@aljustiet that error is unrelated, I'm missing a vulkan-headers dependency in the package, will update shortly...

[russelltg]

package is updated, should be good now.

[aljustiet]

@russelltg It builds, now. It is fixed on my side.
