ValueError: invalid implicit_hyphen_keys: not all keys accounted for (compatibility break note)

[user202729]

Before the switch of Plover source code to use plover_stroke library, it was necessary to specify the number entries in
IMPLICIT_HYPHEN_KEYS. (try stroking 1K5B versus 1K-B.)

If you use the library (before 1.0.0 / C extension), it's possible to either specify or omit it.

At version 1.0.0, it's required (both by independent things that use the plover_stroke library, and by system plugin writers) to omit it, otherwise the error message in the title will be raised.

(... unfortunately, I don't always use the latest version at the moment.)
