Suggesting Fight Stick input fix for N64

[Twitch0815]

I documented this fix sometime ago on
https://github.com/retropie/retropie-setup/wiki/Nintendo-64

Specifically on the
Note for configuring Arcade Joystick or non analogue controller to use N64 correctly section.

I have tested this for most basic fightsticks Ps360+, ZeroDelay, Brooks fighting board and the same fix works each time.

I am making the suggestion that during input configuration when a fight stick board is detected
Brooks, Ps360 +, Zero Delay etc that the way it writes the hat input be changed from
X Axis = "hat(0 Left, 0 Right)"
Y Axis = "hat(0 Up, 0 Down)"
To
X Axis = "hat(0 Left Right)"
Y Axis = "hat(0 Up Down)"
in the InputAutoCfg.ini file

This would allow fightstick boards to be configured correctly for mupen64plus out of the box without users having to apply the fix for a working solution.

Here is an example of my working InputAutoCfg.ini for reference.
