There are two distinct universal_func_types

[glwagner]

There are two functions called universal_func_type. One is defined in UniversalFunctions:

SurfaceFluxes.jl/src/UniversalFunctions.jl

Line 1113 in f83dc86

universal_func_type(::Type{T}) where {T <: BusingerParams} = BusingerType()

and the other is defined in Parameters:

SurfaceFluxes.jl/src/Parameters.jl

Line 25 in f83dc86

universal_func_type(::SurfaceFluxesParameters{FT, AUFPS}) where {FT, AUFPS} = UF.universal_func_type(AUFPS)

The prefix UF in the second is what allows this duplication.

The Parameters version is called here:

SurfaceFluxes.jl/src/SurfaceFluxes.jl

Line 293 in f83dc86

uft = SFP.universal_func_type(param_set)

This is annoying if one needs to extend universal_func_type in an external package, so I propose we eliminate the dichotomy and use just one function.
