Special Support for `.exe` and `.sys` in `maps64`/`maps32`

[sylv256]

Currently, libscemu tries to find dependencies in maps64/maps32 by adding .dll to the end. However, this does not work when the file is a .exe or .sys (for example, when emulating a .sys). The workaround right now is to add .dll to the end of these files so that they can be resolved.

yes i have to refactor this, for now one option is loading it manually:

let map = emu.maps.create_map("something")
map.set_base(0x400000)
map.load("file.sys")

in pyscemu:
emu.load_map("code", "memdump_052D0000.bin", 0x52d0000)
