add app explicit-imports-jl

[ericphanson]

Since we already have an @main this is all that is needed for 1.12's app support. The only question is what to name the CLI app; here I've chosen explicit-imports.

[DilumAluthge]

Is this the name that will be put in the PATH? If so, maybe julia-explicit-imports or explicit-imports-julia would be more explicit?

[ericphanson]

Yeah, it is the name that goes in the PATH. I think those could make sense. Or jl-explicit-imports or something. I wonder if there should be some convention?

I think I'll do explicit-imports-jl here. I like that name and it matches the package (ExplicitImports.jl). If there's a standard convention for julia-tooling packages in a year or two I can do a breaking release and change it then, but I think in the short term there won't be.
