7e101c350c Fixes parameter ordering for new PCACompute function 
Realized after testing this implementation that I had the parameter
names inverted on this. Since they are both output parameters it doesn't
impact functinality so the smoke test still worked.

This change corrects the name order so that the doc is correct.

3b4e6162fe Adds support for PCACompute 
This PR adds support for PCACompute via wrapping one of the opencv
versions with this function signature. A smoke test has been added that
calls the wrapped function and verifies that the parameters are being
passed correctly.

In opencv there are four versions with this function signature, I have
chosen to wrap (what I think is) the most common with the most
parameters.

Link to supported functionality now: https://docs.opencv.org/4.x/d2/de8/group__core__array.html#ga4e2073c7311f292a0648f04c37b73781

e7c254d2f0 Tolerate imprecise result in SolvePoly 
The SolvePoly test TestSolvePoly generates a result that is slightly
imprecise on aarch64 (~2.75e-62) as opposed to a precise result on
x86_64.  This change adjusts the test to tolerate this imprecision.
