Integration Nugget

[mparno]

Sometimes, maps can be more robust by forcing them to have a nonzero minimum slope. This PR enables this by adding a nugget option to the Monotone Integrand class. The new form of map component $T_d(x_{1:d})$ now has an additional fixed parameter $\epsilon\geq 0$ and takes the form

$$ T_d(x_d; x_{1:d-1}) = f(x_{1:d-1},0) + \int_0^{x_d} \quad g(\partial_d f(x_{1:d},t)) + \epsilon \quad dt $$

The value of $\epsilon$ is set in MonotoneComponent construct but is also available in MapOptions. All of the language bindings have been updated to include a nugget option.

Looks great! Would you mind putting an issue up on MParT.jl asking to include this in the MapOptions binding? I can take care of it from the Julia end.
