6822505602 UPDATE: Adds 56 functions in the Statistical section 
Uses statrs for numerical functions

REFACTOR: Put statistical functions on its own module

This might seem counter-intuitive but the wasm build after this refactor
is 1528 bytes smaller :)

fd34e46689 UPDATE: Uses statrs instead of our own erf 
This adds 2630 bytes to the wasm build and a dependency.
It is ok-ish

The idea is that it will help us greatly with the statistical functions

1391f196b5 UPDATE: Adds name validation and exposes it in wasm 
We do a trick I am not proud of. Because all of our errors are Strings,
we don't have a way to separate a name error from an index error,
for instance. What I do in prepend the error with a string that indicates
where it comes from.
