Increased AY volume;

Fixed esxDOS TAP file loading in +3e mode;
Fixed ULA+ IO contention for classic timings (HAM256.TAP has been affected)
Fixed Magic button handling when DivIDE addon is installed;
Attribute port is now accessible only via #FF address in classic timings. This is necessary to prevent a bus conflict when reading ports from addons. Pentagon mode hasn't been affected as it's already used only #FF port in previous versions.

UzixLS

Firmware v20221002

Added support for PCB rev.E;
Added auto CPU frequency feature. When it's enabled:
- Frequency sets to 14MHz on esxdos activity - for fastest loading from SD card;
- Frequency sets to 3.5MHz within ~1ms after #FE port access - this allows to load from tape within turbo mode. Also this improves beeper sound effects;
- Otherwise user configured frequency is used
Added support for ZXKit1 VGA converter. When ZXKit1 setting enabled in menu:
- Hsync on EGA header acts as Csync;
- Vsync on EGA header acts as 14MHz out
Changed PS/2 keyboard mapping:
- Pause has been moved from F12 to F1;
- Reboot has been assigned to F10 and F12 (but still present on Ctrl-Alt-Del / Ctrl-Alt-Backspace)
SD card setting can now be saved;
Allow NMI call when DivMMC's MAPRAM in use (i.e. custom ROM file loaded from SD card);
Fixed compatibility with some PS/2 keyboards, fix random keys sticking;
Fixed incorrect operation of some AY chips when turbo mode is enabled;
Fixed exiting from pause;
Fixed compatibility with addons asserting RSTCPU signal (e.g. Dandanator);
Fixed kempston port decoding - add #DF port for some rare games.
