this change utilizes some of the features from library "frozen", which was included upstream for the grid profile parser. to improve code maintainability, a couple of std::maps mapping strings to values or the other way around were introduced in OpenDTU-OnBattery-specific code at the expense of some flash and computing overhead. library "frozen" offers constexpr versions of map and string, which saves initialization code and offers slightly faster lookups. this brings the binary size down by ~25kB and should provide a small performance improvement at runtime.
