No programming changes in this release except to update module paths.

Changes include:

• updated unit test and benchmark code to use new module path
• moved FromNaNps() up higher in the code to be near similar functions
• corrected mistakes and module path in README.md
• updated go.mod after transferring project back from organization (same owner)

I deleted v0.8.2 released last night because the module path got broken after transferring the project back. Good reminder to rest and get well if you get too sick to go out, instead of messing up simple tasks.

Thanks @fxamacker for catching the mistakes and letting me know.
