8fb4409ebb Adds hasty attempt at dynamic analysis to the MSX ROM handlers. 
Logging for now, for further experimentation.

8be6cb827b Implements MSX interrupt/data request reading register. 
The disk ROM now appears to accept on-disk bytes, but still announces an IO failure.

655b971976 Establishes that there is such as a thing as a Konami SCC. 
Creates one, ensures it appears in memory when intended to, lets it handle reads and writes. It currently does nothing.

185cd3c123 Expands and documents MSX::MemoryMap and MSX::ROMSlotHandler. 
Hopefully to cover all intended use cases.

e349161a53 Rejigs the typing relationship so that use of a typer is not strongly implied by the interface. 
Simultaneously implements typing on the MSX by direct insertion into the key buffer.

5fd0a2b9ea Attempts to pull reimplementations of TAPION and TAPIN better into line with originals. 
Also improves whole flow of the fast tape hack that uses them.

11b73a9c0b Adds preliminary, non-error-checking wiring in of MSX parser alternatives to TAPION and TAPIN. 
As both a prototype of the pending fast tape loading, and to provide for exact behaviour comparison.

0bb24075b6 Immediate fixes: TSX is seemingly TZX 1.21; the tape motor control works the other way around. 
Input is not yet being recognised.

2d892da225 Introduces the MSX keyboard toggle sample source. 
In support of which, it also introduces a means of sample source composition.

Walking towards improving opportunities for composition.
