QoL: detect unsupported engines

[Primekick]

Some users, particularly on mobile, struggle to understand why EasyRPG doesn't detect any playable content when trying to run games made with unsupported engines like RPG Maker versions other than 2kX or similar software (e.g. Wolf RPG Editor).

This PR addresses this issue by implementing a feature that detects games created with commonly encountered unsupported engines. Affects both regular and Android version of the player. The list of known engines consists of:

• RPG Maker XP
• RPG Maker VX
• RPG Maker VX Ace
• RPG Maker MV/MZ
• Wolf RPG Editor

A few screenshots demonstrating the feature:

Jenkins: test this please

Thanks! Looks good.

What could become a problem on mostly our console platforms is Show information for unsupported engines directly on the game list. Reason is that IO performance on many homebrew platforms is ridiculous slow, so fetching these information takes a while :/.

Have to benchmark how awful the performance penalty is.

also worth adding: RPG_RT.rs1. That's an encrypted archive format you can create via the latest Maniac Patch editor. Until somebody reverse engineers the encryption this will not run (even though it's technically a RPG Maker 2k3 game...)

I went & checked a few older RPG95 / SimRPG 95 games for identification.
These names should prove to be reliable targets for a simple file name check, if you'd like to include them:

• SWNAME.DAT + *.RPG -> RPG Maker 95
• SWNAME.DAT + GEOLOGY.DAT -> Sim RPG Maker 95

automatic spaces to tabs seems that added an extra tab
