TWP: Add support for iOS release of Thimbleweed Park

[dwatteau]

Hi,

Back in 2018, I bought the iOS release of Thimbleweed Park:<​https://apps.apple.com/fr/app/thimbleweed-park/id1228969539>

On my MacBook Air M1, it's possible to install and run this iOS release on macOS, when one uses the same Apple account on both App Stores.

That release (1.0.2) is currently not detected by the current 2.10.0git Git HEAD, though.

Here's what I was testing so far. Looks like GAME_XORKEY_566D may be the closest set of keys, but then there's that script error. So, further engine adjustments may be needed (unless a completely new xorKey is actually needed? can't say).

AD_ENTRY1s("ThimbleweedPark.ggpack1", "d6ec4c9073c0c41aa8cb685f7a0d8088", 955615767),	// 1.0.2 release from 2017-09-28

LS_WITH_RUSSIAN

//GAME_XORKEY_56AD,	// GGPackSet::init(): This version of the game is invalid or not supported (yet?)
//GAME_XORKEY_5B6D,	// Not Implemented: value type: 14
GAME_XORKEY_566D,	// "An error occurred in the script: the index '__foobar__' does not exist"
