Fix cnc save/load games

This removes a huge vtable hack to replace cnc save/load games with a similar (hack) as redalert uses

Fix savegame for redalert

v0-r5

Read sha after writing for unknown reasons

merge in upstream

Merge in origin which should fix saving and a few other things

v0-r3

Update switch-utils so that scancode works for text input and so mouse events can be set
a hack that somewhat seems to make saving not crash but there is likely
a bug somewhere
Make it so each game can have it's own keymap
Force game to use a menu even if the intro is skipped
changed default keymap so ZL=left mouse ZR=right mouse

v0-r2

Adding support for redalert

It will look for files in:
sdmc:/switch/redalert/CD1/
sdmc:/switch/redalert/CD2/
sdmc:/switch/redalert/CD3/
sdmc:/switch/redalert/CD4/
sdmc:/switch/redalert/RADVD

For this to work the "CD" directory needs a file called "CD_LABEL" with the text of CD1, CD2, ... indicating the CD

r1

Initial release

To install the game you need to unzip the release onto your sdcard. You will also need the original files from the CD. These are the ones I have
AUD.MIX CCLOCAL.MIX CONQUER.MIX DESEICNH.MIX DESERT.MIX GENERAL.MIX LOCAL.MIX MOVIES.MIX SCORES.MIX SOUNDS.MIX SPEECH.MIX TEMPERAT.MIX TEMPICNH.MIX TRANSIT.MIX UPDATE.MIX UPDATEC.MIX WINTER.MIX WINTICNH.MIX
they are in the directory /switch/cnc/

There is a default keymapping in /switch/cnc/keymap.keys I have them currrently set to
TOUCH_MOUSE=TRUE

DOUBLE_TOUCK_KEYBOARD=TRUE
RSTICK_MOUSE=TRUE
DPAD_ARROWS=TRUE
LSTICK_ARROWS=TRUE
MINUS=ESC
PLUS=ENTER
A=SPACE
