c/p PSTR attribute from Core files
dostring declaration with a macro instead of a scary looking boilerplate
saves varying amount of code space, mostly deals with our key and cmd strings
- clean-up comparison routines and get rid of most of the casts
- reduces total number of calls to terminalRegisterCommand
replace with a func accepting list of commands, which in
turn get instantiated as constexpr PROGMEM arrays
- reduce ram fragmentation, since we don't need to alloc as much
- reduce flash consumption b/c of lambda -> standalone func conversion
rework more namespaces to use `espurna` root
makes internal references much easier (and shorter)
view class is not specific to settings, could use it across the app
remove duplicate code from IR
- allow both new-pwm and analogWrite (Core) implementations
- rework new-pwm initialization, a bit more sane type for pin config
- remove pin setup from lights, everything is handled by provider already
Core prepares and initializes pins when updating duty, new-pwm does this
when pwm_init is called
- rework internals related to value scaling, allow percentage as pwm duty
and value limit (instead of absolute limit set by lights previously)
