Array hash

[pp-mo]

I thought this might cast some light on possible solutions for the #6755 problem.

• specifically, the knockon from Allow derived coord references to be lazy. #6517 which this seems to show.

Rationale:

• since Allow derived coord references to be lazy. #6517 orographies are lazy
• since they are an aux-coord they affect equivalence checking in merge etc
• merge vector signature matching --> Coord.__eq__ --> iris.utils.array_equal
• adopting the hashing approach from _concatenate (see Parallel concatenate #5926) should improve speed
• possibly various benchmarks will show this??

Status:

From a few (30) failing tests, it looks like the old code had the effect of realising some scalar coords?
I'm not clear quite why/how, but I'm going to ignore that for now.

Now trying the benchmarks ...
