[feature] Is it possible to read a config file to store some configuration?

[Freed-Wu]

Such as

mode: "parallel auto"
uniformsize: "fill"
hotkeys:
  left: "h"
  right: "l"
  up: "k"
  down: "j"
  ...

Or just read a python file to configure like ipython and ptpython?

from mulimgviewer.hotkeys import XXX
def user_customize_function()
    ...

def configure(config)
    config.settings.mode = "paralell auto"
    config.settings.uniformsize = "fill"
    config.hotkeys["j"] = XXX
    config.hotkeys["i"] = user_customize_function

A config file seems to be needed in the future. But which features require a config file needs further discussion.

The following functions require a config files. But I think it would introduce more problems. https://github.com/nachifur/MulimgViewer/issues/50

I noticed that you mentioned another issues that this feature is suitable using a config file. https://github.com/nachifur/MulimgViewer/issues/70 https://github.com/nachifur/MulimgViewer/issues/65

Finally, does the introduction of configuration files affect the packaging of the portable exe? It seems to like the portable exe for many people.
