Fails to compile with gcc in Ubuntu 24.04

[jewettaij]

The version of gcc which ships with ubuntu-24.04 does not like the way I am using std::array.
If someone has time to fix this issue, please post a pull request.

Otherwise, I am aware of this problem, and will address it once I have upgrade my compiler to the same version that ubuntu 24.04 is using. (Until then, it's hard to confirm that any changes I would make are working.)

Details:

• The previous commit (330c1e4), introduced a change to the build environment used by Circle-CI to run the unit tests, causing it to use "image: ubuntu-2404:current".
• When the unit tests are run in that environment, this code fails to compile. Evidently, there have been some updates to the gcc compiler (between 22.04 and 24.04).
• I reverted the test so that it uses "ubuntu-2204:current" instead.

I have swept the issue under the rug for now.
