Configuration file support

[dtcyganok]

Description

It would be nice to have an ability to control the SpoofDPI behavior (all of the CLI options) via config file. Usually it's quite an expected feature and a lot of CLI apps have such a feature.

We can create a config file of the following format:

proxy:
    addr: "127.0.0.1"
    port: 8080
    connection:
        timeout: 1
        https:
            window-size: 0
    system-proxy: false
    patterns:
        - "example.com"
dns:
    addr: "8.8.8.8"
    port: 53
    enable-doh: false
    ip-v4-only: false
output:
    silent: false
    debug: false

and specify the path to it via -config-file option.

@Ledorub that's nice! I'd also suggest to read the config file by default instead of using option -config-file. It'd be way more conventional. And it would be nice to have the global/system and the local/user config files on linux systems.
