- 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)

in case some hardware needs it, like ina219 calibration register
that is used by both sensor implementation and hw itself

fix a bug introduced in e4b068ec7d
resolve #2528

dependabot woes

resolves #2500
resolves #2523

- fixing default config values, make sure we take inputs into
  an account and not assume we stay in the 0.0...1.0 range
- use shelly values from tasmota analog sensor impl
- handle edgecase when both resistances are zeroed
- clearer description of available connection schemes

in theory, there is also an option of having *both* up and down
resistors at the same time; right now we simply deduce NTC position by
making it an opposite of resistance. ldrsensor implementation currently
allows to explicitly set sensor position

One namespace for sensor functions and types.
Fix discrepancy between topic and indexed topic funcs.
Energy types fixes, make sure we use known ratios.

Sensor fixes, moving certain pin settings and defaults into the sensor
classes, using those in the actual sensor init code.
Energy is still within the sensor module, pending version bump before moving.

fixes #2507

fixup 4d4b8461dd
(if only the compiler warned about an empty branch...)

plus, move reading into pre()

also split energy info into a separate payload & handler

make sure we have access to magnitude formatters early in the file
more namespacing, where possible

proper support for both conversion directions
ratio object stores the scaling, no need to deduce it through the enum
name anymore

we still don't really enforce incompatible units, though,
but it is unclear at what stage the error should come in

when types are the same, handle things directly in the class base
plus, reduce the amount of explicit comparisons

fix gain multipliers, last two scaled down instead of up
bus voltage is in mV, using datasheet value of lsb (4mV)

address #2516, implement through ratio setting

fixing redirect, authenticate softap connection implicitly
further support needs DHCP helper, at least that's a standard...

plus, pass F(...) strings where String is accepted by the server

similar to the tasmota ota, reset SDK when AP settings somehow are not
set to default *and* we are in safe mode already
move both even earlier in boot, before the wifi setup happens

follow-up a684348b17

using most recent RTOS for reference, allows us to skip Arduino
layer when configuring things. especially useful for UART
re-implementation that does not involve magic pin function modes

adjust our terminal command to really show valid pins and their modes

schedule immediately with module functions, don't wait
more flash-strings in the module and utility functions

support rare condition when body cannot be sent on connect, use poll to send it
don't wait for header line in body, and bail out when done parsing
make sure data is copied into the async variant, and remains there for
the duration of the connection

general async api is... more complicated that it needs to be
until wolfssl / brssl port is here, though, there is no other choice
secureclient config becomes a simple struct, pending further rework
