Experimental support of SIMD (go 1.26)

[samber]

A few helpers might have SIMD variants:

• Sum
• Mean
• Min
• Max
• Clamp
• SumBy
• MeanBy
• Product
• Abs
• Sqrt
• Contains
• Every
• Some
• None
• IndexOf
• HasPrefix / HasSuffix
• Find / FindIndexOf / FindLastIndexOf
• FindOrElse
• MinIndex / MaxIndex
• More ?

See #801

We won't recode arrow in lo, but I'm open to discussion for a high-level pipelining abstraction. Example:

• Pythagoras's theorem: Sqrt(Mul(a, a), Mul(b, b))
• Average age of adults: Mean(GreaterThan(18, age))
