READ TOC receives its allocation length from the initiator’s CDB and accepts values up to 65535 bytes. The controller’s transfer buffer is normally only 4096 bytes, so using that value directly could overrun the buffer and report more data than can be transferred.
Clamp the response length to the available buffer size and clear only that bounded range before constructing the response. Also bound the start-track scan before dereferencing the track vector, allowing a lead-out (0xAA) request to safely produce its descriptor when no matching track exists.
Add regression tests for the maximum allocation length and for READ TOC lead-out handling.

* Don't resize DiskCache without a file
DiskCache computes its size from a file.
Skip ResizeCache Without file (i.e. 'empty' CD)

* Implement ModeSelect for scsicd
and honor sector size setting.
DEC's VMS can't handle 2k sector sizes and uses ModeSelect6 to set the
sector size to 512 bytes.

* resize cache after change of sector size
The disk cache is based on sector size and must be resized when the
sector size changes.
Disk::ResizeCache needs a `raw` parameter, make this value accessible
from the current cache.
