variables imported via using in previous notebooks are not visible

[disberd]

Right now the package relies on Base.names to find out all the variables that are defined in the submodule containing the target of @frompackage.
This unfortunately does not expose the names of the variables that are imported in a module when simply using other packages.
See https://discourse.julialang.org/t/get-all-names-accessible-from-a-module/98492

This means that the behavior of @frompackage can not exactly mimic the chain of inclusions inside of the target Package source code.

Take as example the two notebooks inner_notebook1.jl and inner_notebook2.jl in the TestPackage

While inner_notebook2.jl should still se BenchmarkTools as it's imported within inner_notebook1.jl, this does not happen inside Pluto:

The current workaround is to also explicitly use the package also inside inner_notebook2.jl. So translate the macrocall from

@fromparent import *

into

@fromparent begin
    import *
    using >.BenchmarkTools
end

It seems this also applies to names explicitly imported with the synthax using Package: name. Doing import Package: name does instead make the imported name visible also when calling using * in @fromparent
