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.

It's not OK to call seek() here. Instead, add a function which can read

this function to all the data bytes, rather than just the first one.

seekToPattern() can skip the index hole if it doesn't find the
SYNC pattern. If this happens too close to the end of the flux
stream, it can result in a conflicted sector. In this case,
discard the sector.
