Rename percision to accuracy

[AdamGS]

Summary

This PR renames the Precision enum that we use to do array hashing and equality checks to Accuracy, as we already have a Precision enum we use for stats, that is also part of the binary format.

API Changes

Just the renamed enum, which should be relatively minor.

accuracy is the wrong word

[joseph-isaacs]

exactness?

[AdamGS]

how about splitting it into two functions on the same trait? the enum seems confusing
