Adding an OASES model

[pabloborys]

Hi, I understand that adding models is one of the features of UnderwaterAcoustics.jl. I am wondering how hard it would be to add Oases to the available models. Thanks.

I've personally not used OASES much, but shouldn't be that hard. Just need to define an Oases type and implement each of the interface functions for the model:

function check(::Type{Oases}, env)
function arrivals(model::Oases, tx, rx)
function transfercoef(model::Oases, tx, rx)
function eigenrays(model::Oases, tx, rx)
function rays(model::Oases, tx, θ, rmax)

by making equivalent calls in OASES.
