6b990a9f51 Overhaul the TPI stuff; now both the drive and the layout have a TPI setting, 
which must be set.

466c3c34e5 Replace the Error() object with an error() function which takes fmt 
formatspecs, making for much cleaner code. Reformatted everything.

This actually happened in multiple steps but then I corrupted my local
repository and I had to recover from the working tree.

f8257e697a D88: Use the data length field to seek past any extra data. 
This will effectively ignore the field length if it is shorter
than the sector size (or 0).

D88/NFD: Add physical layout before adding sector.

ef5f7ec9c3 D88/NFD: Add physical layout before adding sector. 
Partially fixes #603, it is still busted if the number of
tracks is specified larger than what is in the image, which
used to work.

69c60c4026 Force density setting for D88/NFD. 
This fixes #560 (partially).

I do not understand how the protobuf parsing stuff works enough
to make it detect optional fields.

415aa82a6f The top-level tracks and heads fields are now inferred automatically from the 
layout if not set, so we don't have to set them everywhere.

498558c2b1 Add n88basic sector gaps to d88 reader for PC-88 DD disks. 
The values used for 1.2MB HD disks are too narrow for the
PC-88's disk controller.

adff739a5d Partial conversion to do automatic scaling of flux based on the disk rotation 
speed. Although, something seems to have broken for 5.25" disks.

the mapper (where appropriate).

ba3f806616 Move a lot of drive parameters into a toplevel drive{} config rather than 
leaving them in the source/sink configs (which means they have to be set
twice).

dfb461b05c D88: Add 2D (40 track double density) support. 
This assumes a 360rpm drive, and double stepping.

If fluxengine supports the concept of 40 vs 80 track drives in the
future, it might make sense for this to assume a 300rpm drive
instead.

04b91377c9 Use per-track encoding specified in D88 files. 
This supports varying sector sizes, counts, and modulation on
a per-track basis. It also supports writing sectors in the
original order.

8a3cd14723 Add minimal D88 image format reader. 
This implements a subset of D88, only supporting the first floppy
in an image. It only supports images with equal sector sizes,
equal numbers of sectors per track, and no bad sectors.
