Some `display` methods require the IOStream to be still open

This makes it hard to use the readmeta method with the function as first argument (which can be used with the do-block syntax), instead

julia> using ObjectFile

julia> io = open("./librdkitcffi.dll", "r")
IOStream(<file ./librdkitcffi.dll>)

julia> oh = readmeta(io)
COFF Handle (64-bit)

julia> [s for s in Symbols(oh) if contains(symbol_name(s), r"get_(|q)mol")]
3-element Vector{COFFSymbolRef{COFFHandle{IOStream}}}:

julia> close(io)

works, but it requires more manual steps.
