Make slight tweaks for Debug builds.

[RyanWollaeger]

Description

Testing with a Debug build of a dependent code revealed a comparison of the same constants throws an assertion.

Changes

• Modify memcmp usage in == overload comparing physical constants.
• Update spiner submodule for fix of a recently added assert.

@Yurlungur would it be reasonable to convert the bit-wise comparison in the overload to comparing the member data with tolerances (to permit, e.g. 1e-15 differences in units)? Or is that maybe not in the spirit of this comparison?

I think that would be fine. The current implementation is just laziness on my part I think.

Will make that change quickly here then - thanks!

Just made the eps-comparison modification (the memcmp is much more succinct).
