Beech (BBC Micro Emulator) 0.4

It’s been over 10 years but I’ve been fiddling with Beech again and fixed some issues:

• Builds on Visual Studio 2026.
• Double-sided disks work properly. (Head select in 8271 emulation was broken.)
• Major updates to MODE 7. Hold/release in SAA5050 emulation now works correctly, which fixes a lot of MODE 7 graphics.
