Importing a sheet guessed which column was the controller name and which was
the sign text, then silently acted on the guess. On a sheet whose headers it
did not recognise, the guess fell through to "first column", which is usually
the row number — so the destinations came out named 1, 2, 3.
Now the import opens a preview: the two columns are dropdowns, seeded with the
guess and showing a sample of each, above a table of exactly what will be
created. Nothing is imported until it looks right.
The guessing itself is better too:
- a top row of words above rows containing numbers is treated as a header
even when none of its labels are recognised
- with no recognisable columns, the column carrying the longest words wins
- one recognised column stands in for the other, since a destination's name
is usually exactly what the sign shows, rather than picking at random
- a truncated name no longer keeps a trailing space, which would also stop it
matching an existing destination on a later import
Also adds custom sign sizes, for boards that are not one of the three fitted
models. Widths snap to a multiple of 8 since the record stores width in bytes.

Samples
Real files from the operator this was built for, used by the test suite as the reference for "what TP5 actually produces".
EXPRESS.tp5— a TP5 project: the destination list with its textEXPRESS 1.td5— the same list exported for the bus, made by TP5 itself. This is the filetest/roundtrip.mjsrebuilds byte-for-byte.desto-test.xlsx— a small sheet in the layout of the template these buses ship with, for exercising spreadsheet import.
The .td5/.tp5 pair is the ground truth for the whole format. Replacing them
with anything else means the round-trip test is no longer checking against a
known-good TP5 export.
