Add support for Modena ES-15-SKY water heater

Issue #2008

- a lot of guesswork, and placeholders (eg for mode). Manual does not
match the protocol info, but suggests that tank volume is wrong (and
should maybe be read-only) and modes are much reduced (and should map
to standard, morning, afternoon or something like that)
