Andy McFadden 37855c8f8e Allow explicit widths in project/platform symbols, part 4 (of 4)
Handle situation where a symbol wraps around a bank.  Updated
2021-external-symbols for that, and to test the behavior when file
data and an external symbol overlap.

The bank-wrap test turned up a bug in Merlin 32.  A workaround has
been added.

Updated documentation to explain widths.
