Poom goes the dynamite

New Platform: OpenDingux
Gcw0, RG350/280/300 devices should be able to use the fake08_gcw0.opk file. Thanks to @gameblabla for the initial port

3ds:

• improve image quality of non-integer scaled images by using wide mode
• fix loading multi cart games

Miyoo Mini:

• fix cart data saving and loading

Bittboy:

• Add a 240x240 rendering mode

All platforms:

• honor print mode defaults poked into memory
• refactor cartdata serialization and deserialization to work consistently across CPU architectures
• Add reset function
• Fix regression in mget bounds checking
• support extra arguments to poke2 and poke4
• Fix map default values if width has been changed and/or large map is being used
• Honor suppress pause menu flag
• Fix tline wrapping
• Fix passing a param to load if there is a nil breadcrumb
• Added support for getting key presses via stat (currently only supported on debug builds- Thanks @DPS2004)

Notable games that are now playable:
Poom and Terra (Doom and Terraria demakes), plus Jelpi works correctly again

Known issues:
Poom does not work on Bittboy platform. Unsure of root issue, but it would probably be unplayably slow anyway
