When loaders or savers throw errors, FileIO.jl outputs error messages to `stderr` and `stdout` without `Logging` functions or macros.  
The messages are helpful in most cases, but can mess up proper log handling.

```julia-repl
julia> using FileIO

julia> try; load(IOBuffer("\x93NUMPY!!!BROKEN!!!")); catch; end # just an example
Error encountered while load Stream{DataFormat{:NPY}, IOBuffer, Nothing}(IOBuffer(data=UInt8[...], readable=true, writable=false, seekable=true, append=false, size=18, maxsize=Inf, ptr=1, mark=-1), nothing).

Fatal error:

julia> pkgversion(FileIO)
v"1.16.3"

julia> versioninfo()

Of course we can use Supressor.jl as a general measure.  
Is there any way to suppress or redirect `FileIO`(-specific) error messages?  
Or is it possible to make changes related to that in FileIO.jl **v1**?

In the first place, it should be fully expected that externally supplied files are broken or unsupported.  
The “Fatal error” seems to be too casual about “fate”.
