Switch to using native type arithmetic (no more codegen!)

[jscheiny]

This PR removes the old clunky code gen to compute multiplication, addition, and subtraction tables. Now we do this all natively in typescript using fun tuple math!

Note this generally is a good thing and largely removes the exponent restrictions previously in place. However, to make this work I decided to ditch some of the exponentiation and root functionality. This PR has the following breaking changes:

• Exponents are now represented as numbers instead of strings
• Removed all square root / cube root / nth root functionality (e.g. functions like sqrt() and cbrt())
• Removed arbitrary exponentiation (toThe(power) is gone). All that is left is squared() and cubed() which now just work all the time!
