Bessel-corrected std in ZScore transformation

[adelinehillier]

We might as well apply Bessel's correction since this is a sample standard deviation.

I guess this has a pretty small effect for most of our cases. corrected=true is the default --- do we know why we previously wrote corrected=false?

Seems like just a mistake?

@adelinehillier, @glwagner tests fail because, I presume,

ParameterEstimocean.jl/test/test_transformations.jl

Line 53 in 3e4489b

μ, σ = mean(sliced_raw_observations), sqrt(cov(sliced_raw_observations; corrected=false))

needs to change to corrected = true. Am I right?

[navidcy]

@glwagner is this stale?

[glwagner]

We should probably put this change in, not sure why tests are failing though since this does very little.

[navidcy]

Probs the tests were run on an outdated version -- let's see now.

22c54d5 fixed the tests
