apple2: encoder: Fix writing of "FF40"
...
I was writing "FF40" as "FF48": 1111 1111 0000 instead of 1111 1111 00.
This sequence of four zeros will not allow the real hardware to synchronize
to the bitstream.
With this change, I was able to boot a DOS 3.3 disk I rearranged into
"physical" order; some 'there's a disk error' raspberries occur (probably
indicating a data error within a sector) during the boot process, so
something is still obviously marginal, but this is a huge step forward.

Fix crash when reading disks written on real apple2
...
`readRaw8` throws an exception if you run out of data. This did not
turn up during my testing, because I was reading back a disk written by
fluxengine, so everything was aligned to the index pulse and no sector
ever straddled a revolution. On a "real" apple2-written disk, this was
not the case.
Incidentally, the "extra 0" problem exists on a real apple2-written
floppy as well.
