Add argument to specify path to ROMs

[andrewrabert]

Adds a new argument -d: to specify the directory to use for ROMs.

[UnBeatWaterGH]

I would maybe separate -d: from the others since directories aren't related to audio. Something like this:

...
-a:<device_number>             Set Audio Device index.
-ab:<page_size>:[page_count]   Set Audio Buffer size.

-d:<rom_path>                  Set ROM directory.

-mk2                           Use SC-55mk2 ROM set.
-st                            Use SC-55st ROM set.
...

Good idea. Changed & force pushed.

or you can make directory with rom name and automatic choose the right one when you type --mk1, --jv880 , ...

Being able to specify the folder via an argument is useful on Linux where the application is usually installed to a location where only the root user has write access too.
