It looks a bit sloppy to hardcode so many constants in a single file: `src/gauss_quadrature/legendre.rs`. Isn't it possible to generate them with the help of rust macros in the same way Julia uses metaprogramming?

Integrate supports a variety of numerical integration techniques: - Newton-Cotes methods:
- Rectangle Rule.
- Trapezoidal Rule.
- Simpson's Rule.
- Newton's 3/8 Rule.
- Gauss-Legendre.
- Gauss-Laguerre.
- Gauss-Hermite.
- Gauss-Chebyshev First Kind.
- Gauss-Chebyshev Second Kind.
- Adaptive Simpson's method
Additionally, compile time floating-point evaluation is limited. When I looked around recently, I didn't see a rust equivalent of gcem; any kind of transcendental function evaluation (which finding Gaussian quadrature points absolutely would require) would not allow compile-time evaluation.
