encode_test fails with Vips::Error: unable to call VipsForeignSaveJp2kBuffer: unknown option profile

[anitagraham]

I am running the test suite (in preparation for submitting a PR) and getting this failure, which is not, I think, related to the PR. Here is the stack trace:

I am running

• vips-8.11.3-Wed Aug 11 09:29:27 UTC 2021
• dragonfly_libvips 2.4.2
• Ruby 2.7.2, 3.02
• macOS 11.6

The doc for jp2ksave doesn't include :profile in the options list.
(Checked pngsave - does include :profile)

If it is as simple as adding jp2k to list of options without profile support I can submit a PR for that.
Is there anywhere else to look?

thanks,

Anita
