Log message:
imath: update to 3.1.12.

## Version 3.1.12 (September 9, 2024)

Patch release with a small fix:

* Support for compiling half.h with hip-runtime-amd

Also, the v3.1.11 release had improper versioning in its cmake and
pkgconf configuration files. This is now fixed.

Log message:
imath: update to 3.1.11.

## Version 3.1.11 (February 28, 2024)

Patch release with small build fix:

- Add explicit `std::` namespace for `isfinite` in `ImathFun.cpp`

This release also introduces the practice of signing release artifacts
via [sigstore](https://www.sigstore.dev).

imath: update to 3.1.10.

## Version 3.1.10 (January 26, 2024)

Patch release with various build/bug fixes.

Build fixes:

  - Fix a problem where downstream projects using Imath would build
    python bindings even if they weren't requested.
  - Fix for missing `std::bit_cast`
  - Fix missing/necessary use of IMATH_HOSTDEVICE
  - IMATH_INSTALL_PKG_CONFIG is now on by default, even on Windows
  - Fix calling default constructor by uniform init in TypeTraits
  - Fix redundant PYIMATH_EXPORTS causing compile issues on Windows Clang
  - Update to SO versioning policy:

    This change adopts a policy of appending the ``MAJOR.MINOR.PATCH``
    software release name to the ``SONAME`` to form the real name of the
    shared library.

    See [website/install.rst](website/install.rst) and [PR
    #339](https://github.com/AcademySoftwareFoundation/openexr/pull/339)
    for more details.

Bug fixes:

  - Fix half to float giving wrong results on older x86_64 CPUs on Windows

Other changes:

  - succ()/pred() now use std::nextafter().
  - Expand epsilon bounds for m44x pyImath test.
  - Rename "docs" to "website".
  - Add missing copyright/license identifiers.

Log message:
imath: update to 3.1.9.

## Version 3.1.9 (May 31, 2023)

Patch release that fixes an correct .so version number introduced in
v3.1.8. All Imath library functionality is compatible with v3.1.8.

This release also reverts
[#305](https://github.com/AcademySoftwareFoundation/Imath/pull/305),
which inadvertently introduced additional python bindings in v3.1.8
that altered the ABI of ``libPyImath``. ``libPyImath`` is now
ABI-compatible with v3.1.7 and previous releases.

Log message:
imath: really bump ABI depends
