Supressing harmless warning and error messages

[ali-ramadhan]

Right now anyone using Oceananigans for the first time sees Casette warnings (vchuravy/GPUifyLoops.jl#94) and CUDA warnings on the CPU.

They're harmless issues but give the feeling of an unstable package.

Would be good to suppress them somehow.

This package might help: https://github.com/JuliaIO/Suppressor.jl

What I see on a CPU:

WARNING: Method definition recurse(Cassette.Context{N, M, T, P, B, H} where H<:Union{Cassette.DisableHooks, Nothing} where B<:Union{Nothing, Base.IdDict{Module, Base.Dict{Symbol, Cassette.BindingMeta}}} where P<:Cassette.AbstractPass where T<:Union{Nothing, Cassette.Tag{N, X, E} where E where X where N<:Cassette.AbstractContextName} where M where N<:Cassette.AbstractContextName, Any...) in module Cassette at /home/alir/.julia/packages/Cassette/IwsFs/src/overdub.jl:550 overwritten in module GPUifyLoops at /home/alir/.julia/packages/Cassette/IwsFs/src/overdub.jl:550.

No need to worry about CUDA package errors anymore!
