exrmetrics: compilation error

[0-wiz-0]

While updating the openexr package in pkgsrc, I noticed the following compilation error on NetBSD-10.99.12/amd64 with gcc 12.4.0:

/scratch/graphics/openexr/work/openexr-3.3.0/src/bin/exrmetrics/exrmetrics.cpp: In function 'void exrmetrics(const char*, const char*, int, Imf_3_3::Compression, float, int)':

Following the compiler's suggestion fixes the build:

fix lgtm, thanks; do you want to submit or PR, or simply have us apply it?

I've made a patch but then noticed that I have to sign a contribution document, which is quite overkill for such an easy patch - so please just commit it yourself.
Thank you!
