Replace dash with hard hyphen in myuplink entity names

[astrandb]

Breaking change

Proposed change

Dashes are sometimes(?) removed when HA creates entity names. This can result in unreadable entity names e.g. (EBT101-BT6) is created and displayed as (EBT101BT6). Names of this style are common in the meta-data from MyUplink API.
We here replace the dash in an entity name with a hard hyphen.
