FileIO not loading / requiring dependency AVSfldIO properly about fileio.jl HOT 2 CLOSED

To be clear, FileIO currently does not handle package installation. Thus AVSfldIO must be installed somewhere in the load path to work:

julia> LOAD_PATH
3-element Vector{String}:
 "@" # (IIUC) current project environment
 "@v#.#" # root environment; ~/.julia/environments/v1.7/Project.toml
 "@stdlib"

Pkg.instantiate only works if AVSfldIO is listed as a dependency in Project.toml; so one option is to still keep MIRTio in the Project.toml in JeffFessler/MIRT.jl#108 but does not use using MIRTio explicitly; this guarantees that any environment with MIRT installed has MIRTio available in the load path.

Thanks for the helpful explanation. I misunderstood how magical FileIO is...
