Custom mem read

[grahambates]

I've made a change to the read-memory command in FS-UAE and WinUAE to allow reading from custom register addresses. This unblocks a few features in the debugger:

Variables pointing to addresses in this range will now correctly display their values:

You can read custom addresses in the Amiga: View memory command:

I've also implemented a new panel to list these alongside CPU registers when debugging.

cool. can you support CustomSpecial.pth, CustomSpecial.ptl to combine pointer registers into one as in https://github.com/BartmanAbyss/vscode-amiga-debug/blob/master/src/client/debugger/customregs.tsx#L84 ?

I've made this change and also refactored a bit to move a bit more logic into the BaseNode class to eliminate some repetition around value formatting etc.

We could definitely make more use of the tree view to group related fields and extract bit components from register values. I implemented something similar on The Other Extension 🙂:

I can look at porting this if you're interested (maybe as a separate PR). It's a bit of a different implementation because we use the variables list for registers, but I can definitely reuse the grouping logic. I'm guessing we'd want it in the profiler register list too.

sure. that sounds fine. I'm doing something similar but more hard-coded for the DMA/blitter tooltips and the screen tooltips.
probably a bit harder for the profiler register list because I had to switch to a virtual list due to performance reasons, Maybe it's easier there to just add it to the tooltip.
