In CUE files `FILE` is a stateful, global declaration that applies to
all following `TRACK`s. `sotn-disk` was treating `FILE` declarations as
`TRACK` delimiters which would result in incorrect parsing of CUE files
with a single `FILE`, but multiple tracks.
Now when reading a `FILE` declaration, the path is stored and processing
continues. A `TRACK` declaration will use the previously defined path,
and if a previous track had been started, append that previous track to
the list.
This also builds `sotn-disk` using the local repository instead of
pulling the latest commit from GitHub. The target depends on `sotn-disk`
sources and will rebuild as necessary (or with `make
~/go/bin/sotn-disk`).
As an aside,
[pull/232](https://github.com/Xeeynamo/sotn-decomp/pull/232) ran into
this same error, but fixes in a slightly different way that leaves side
effects that may make supporting things like `INDEX` (for extracting the
placeholder audio, for example) more error prone in the future.
