Create Transformation with a single pipeline projection

[evetion]

Now to setup a pipeline, we need to handle the C API:

julia> pipe = Proj.proj_create("+proj=pipeline +step +proj=unitconvert +xy_in=deg +z_in=m +xy_out=rad +z_out=m +step +inv +proj=longlat +a=6378136.3 +rf=298.257 +e=0.08181922146 +step +proj=cart +a=6378136.3 +rf=298.257 +step +inv +proj=cart +ellps=WGS84 +step +proj=unitconvert +xy_in=rad +z_in=m +xy_out=deg +z_out=m +step +proj=axisswap +order=2,1")
Ptr{Nothing} @0x00000001254061d0

julia> Proj.proj_trans(pipe, Proj.PJ_FWD, (0,0,0))
4-element Proj.Coord:
