structure, overrides, strong time types

actually use the analog sensor base to read
(and fixing yet another pinmode accident)

fixed structure, overrides. strong time types

updated structure, overrides. strong time type
testing timesource changes. this should work, but might need to tweak
things if it starts to fail b/c of flash code loads

conversion is not working for signed ints, only unsigned

do not force to implement constructor, just update vtable
continue testing with bme280 class, update structure

make sure there's an option for direct address setup
sensor updates are wip, since base sensor code is also changing

use bitset when locking, avoid manual index & mask calculation
update check() to use boolean logic instead of returning int status
remove wip address-range, just use the {begin, end} pair
uint8_t instead of unsigned char when dealing with data

Avoid confusion between ref and pointer when looping over sensors
Re-use helper class in the magnitude object as well

Remove custom code related to filter movement, just use unique_ptr
Plus, updates filter code to use stl vector where possible

Experimening with dynamic cls id. Perhaps this should be something
else... but, at least there are no longer any header-defined values.

preemptive fix for the issue resolved in the 3.1.0

As mentioned in the #2491
Hides parent element when these groups are empty

Added support for Itead Sonoff POW R3 (https://itead.cc/product/sonoff-powr3/)

This device is essentially the same as the POW R2, except:
- the relay is a normally closed type,
- the current and power ratings of the device are higher.

fixes #2491

While I am still hesitant to call this an improvement,
at least this makes part of the installation slightly faster

since it won't decide between String and StringView,
manually direct it to the StringView

also normalize token values of particle measurements

clangd does not like integer SUPPORT flags and `||`

amends e51e259f02
fixing incorrect conversion from kelvin, and also add full
conversion from possible farenheit source (if that ever happens)

experimenting with the idea of unit conversion... while a table-like
approach will work and will be slightly shorter, it would not have the
specific type checks and constexpr still does not play well with lambdas

plus, any conversion function referenced as a pointer will not really
be a constexpr (...and still require c++17 to work correctly when iterating)

cursor no longer calculates 'offset' but stores the absolute position
this also helps not introducing that specific math to the outside code

more const-correctness fixes and general accessors instead of plain structs
access and modification, where specific ctor or helper method should've
been used instead

Restore behaviour from dd12251e43
7ba1283024 unintentionally removed it
Instead of reverting to the 'atof' code, just use the provided string
as-is via RawJson (aka `serialized()` in the v6)

Note that the old approach may have caused some silent data loss b/c the
data could have been stored in 'double' or 'u64', where the ArduinoJson
only stores 'u32' and 'float' in it's internal buffer and does not (really)
warn us about any type incompatibilities.
(at least by default. but, the alternative is to store all floating point
numbers as 'double' internally, see ArduinoJson/Configuration.hpp)

resolves #2503

both heap size values should be u32

removes the extra 'save' button from the ui and the code that handles it
also make sure to use the updated foreach_prefix when looking for the
match in the settings

resolve #2502

Cursor is in a weird spot, by being both the pointer to the data and the
read-range that is used of specify the range in which we operate
Next TODO would be to move even more things to 'const', but that would
at least require to rework the cursor object and also remove it from the
members list.

Also, try to fix the API helper objects to persist the referenced struct
(best effort only, though, it is still possible to break things when not careful)

also rework internals of the analog and ntc sensor classes to use
explicit delays and update it's comments
