0aed615ee5 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.

79eec41bcd Revamp how extra zeros are handled 
It's not OK to call seek() here. Instead, add a function which can read
an apple 8-bit flux value in terms of readRaw8 and readRawBits. Apply
this function to all the data bytes, rather than just the first one.

87cb4b6d18 Add apple2 encoder 
This is tested with encodedecodetest.sh but is not tested on HW yet.
It's likely that the sector order (interleave) doesn't match real systems.

d028db1ba3 northstar: Improve decode a little more. 
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.

4cbd19d2e5 fluxmap: Don't push_back() if Fluxmap begins with F_DESYNC. 
Fluxmap::split() creates a 0-length Fluxmap if the Fluxmap
begins with F_DESYNC.  Fix this by not doing push_back()
if a F_DESYNC is encountered at the start of the Fluxmap.

b4489b9402 Add support for PDP-11 RX-50 disks 
According to my source [https://www.cbmstuff.com/forum/showthread.php?tid=634] the format of RX-50 is

 * single sided
 * 80 tracks
 * 10 sectors per track
 * 96 tpi (tracks per inch)
 * 300 rpm (revolutions per minute)
 * 250 KHz data rate

I have a disk labeled
```
BL-T540E-MC
CZUFDE0 MICRO PDP-11
USER TESTS
© 1983, 1894
DIGITAL EQUIPMENT CORP.
```
and stamped 14131.

The image read all sectors and the content looks plausible.  `strings` on it says things like
```
$ strings rx50.img  | grep -i pdp
; This file implements the USER FRIENDLY Diagnostic for the MICRO PDP11 & 11/73
```
however, I don't have an emulator or other system to use the disk image with so
I can't 100% vouch for the image being complete and correct.

a67b7c80c1 Rework the visualiser to look better, maybe? Also fiddle with the logger 
somewhat. There's a pending problem where it's not safe to send mutable objects
through the logger to the visualiser, which will need work.
