* emon: configure ratios without reboot
* settings: serialize() support
* debug: use vsnprintf from newlib, not from sdk
* settings/experimental: show defaults via `get`
* emon: override base methods, fix defaults
* sensor/emon: expose internal index calculation
- refactor configuration to use the correct index when accessing indexed
sensor methods. store index value on magnitude, refactor loops to
accomodate this new functionality
- rename slot(index) -> description(index), since we use 'slot' as
numeric value
- general conversion from .ino modules into a separate .cpp files
- clean-up internal headers, place libraries into .h. guard .cpp with _SUPPORT flags
- fix some instances of shared variables instead of public methods
- tweak build system to still build a single source file via os environment variable ESPURNA_BUILD_SINGLE_SOURCE
* debug: store boot log
* order
* roll single header
* hide when not implemented
* fix capacity check
* dependencies
* refactor names, can just use malloc
* settings formatting
* dbgBuf prefix
* show size
* release memory after buffer is displayed
* fix uptime unused warning, combine printer
* comments
* use arg flag instead of static to handle boot
* ci test fix
* Hide whole info() without debug
* typo
* cleanup setDebugOutput condition
- mask is defined as (relay# status << number)
- transparently handle base-2 and base-10 numbers
- if the relay mode requires us to save the mask, it will be saved as base-2
- update every dynamicjsonbuffer with fixed size constructor argument
- change to ws callback registration to use a class builder (just cosmetic)
- test multiple ws data callbacks for each module
- remove some of the static strings in favour of ws data callback
- improve sensor ws callback data size, remove duplicated strings
- use static buffer in wsDebugSend
- postpone wsSend until loop, implement wsPost to allow other modules to queue message callbacks. remove Ticker based ws callbacks for data
- update WebUI files
- add httpupdate ota impelementation
- move async ota into a separate module
- support bearssl & axtls through wificlientsecure
- allow to disable arduino ide ota module
* debug: heap fragmentation stat
* Rework method detection
- return check integral type as a result of detection instead of method type
- type-tagging instead of enable_if
* fix alias
* typo
* only need one bool_type instance
* Move heap debug into HeapStats header
- don't show fragmentation stats on the first call
- prettify fragmentation display
- pack function params into helper struct
- naming
* pass external flag instead
* add missing prototypes
- store system crash counter and reset reason in rtcmem instead of eeprom
- store relay state mask in rtc in addition to the eeprom
- store relay state in eeprom only when boot mode requires it
- simplify relay state mask calculation / reading using std::bitset
- light state save and restore
- energy total save and restore
